If l 1m, then <1 is a right angle
Right angle is an angle of 90 degrees while complementary angles add up to 90 degrees.
What are complementary angles and right angles?When the sum of two angles is 90°, then the angles are known as complementary angles.
A right angle is an angle of 90°.
Perpendicular lines are lines that intersect at a 90° angle. Perpendicular lines forms a right angle.
The complementary angle theorem states, "If two angles are complementary to the same angle, then they are congruent to each other".

The z-score of the lowest temperature is −2.49. What is the lowest temperature? Round your result to the one’s place.
The lowest temperature with a z score of of -2.49 is 24.0 ˚F
How to find the temperature with a z score of -2.49Z scores, measures the amount of standard deviation sample X is from mean. the formula is below
z = (X - μ) / σ
Definition of variables
mean, μ = 4.4˚F
standard deviation, σ = 12.2 ˚F
X = lowest temperature
z = -2.49
substituting into the formula
-2.49 = (X - μ) / σ
-2.49 = (X - 64.4) / 12.2
-2.49 * 12.2 = X - 64.4
-30.378 + 64.4 = X

3. The number of pupils in Team A to the number of pupils in Team B is in the ratio 7:6. If 45 pupils are transferred from Team A to Team B, the ratio will become 2: 3. How many pupils are there in each team?
Answers:
Team A = 175 people
Team B = 150 people
This is before the 45 students transfer from A to B.
===========================================================
Explanation:
x = number of people in team A
y = number of people in team B
These counts are before the 45 pupils transfer from A to B.
The counts are in ratio 7:6, which means,
x/y = 7/6
6x = 7y
x = 7y/6
If we subtract 45 people from team A, we have x-45 people left. Those 45 people go to team B to have y+45 pupils there.
The quantities x-45 and y+45 are in ratio 2:3, so,
(x-45)/(y+45) = 2/3
3(x-45) = 2(y+45)
3x-135 = 2y+90
3(7y/6)-135 = 2y+90 .... plug in x = 7y/6
21y/6 - 135 = 2y+90
6*( 21y/6 - 135 ) = 6*(2y+90)
21y-810 = 12y+540
21y-12y = 540+810
9y = 1350
y = 1350/9
y = 150
x = 7y/6
x = 7(150)/6
x = 175
We have 175 people on team A, and 150 people on team B.
This is before the 45 students transfer from A to B.
-------------------
Check:
x/y = 175/150 = (7*25)/(6*50) = 7/6
This shows x and y are in ratio 7:6 to match the instructions.
x-45 = 175-45 = 130
y+45 = 150+45 = 195
(x-45)/(y+45) = 130/195 = (2*65)/(3*65) = 2/3
And we have the updated counts in the ratio 2:3, which matches the stated info in the instructions. The answers are fully confirmed.
Which congruence theorem can be used to prove that the triangles are congruent AAS SSS SAS HL?
Side-Angle-Side (SAS) Rule prove the congruency of the triangle
What is a triangle ?
A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.
Triangles can be divided into three sorts based on the lengths of their sides, and they are: Scalene. Isosceles. Equilateral.
The Side-Angle-Side rule is used to demonstrate whether a set of triangles is congruent. According to the SAS rule, two sides and the included angle of one triangle must equal two sides and the included angle of another triangle in order for the two triangles to be considered congruent.

The width of a rectangular slab of concrete is 10m less than the length. The area is 24 m ^2
The width and the length of the slab are 2 meters and 12 meters, respectively
How to determine the dimensions of the slab?From the question, we have the following parameters that can be used in our computation:
Width of a rectangular slab of concrete = 10m less than the length.
Area = 24 m²
These parameters can be represented as
Width = Length - 10
Area = Length * Width
So, we have
w = l - 10
A = lw
Also, we have
A = 24
Substitute w = l - 10 in A = lw
A = l(l - 10)
So, we have
l(l - 10) = 24
Expand
l² - 10l = 24
This gives
l² - 10l - 24 = 0
Expand
l² + 2l - 12l - 24 = 0
Factorize
(l + 2)(l - 12) = 0
So, we have
l = -2 and l = 12
The length cannot be negative
So, we have
l = 12
Recall that
w = l - 10
So, we have
w = 12 - 10
Evaluate
w = 2
Hence, the dimensions are 2 meters and 12 meters, respectively

When the prices are both increased by £20, the ratio becomes 5:2
When the prices are both reduced by £5, the ratio becomes 5:1
Express the ratio x : y in its lowest terms.
Prices of two ratios in the ratio is 4 : 1.
What do you mean by ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Ratios can be classified into two types. One is part to part ratio and the other is part to whole ratio. The part-to-part ratio denotes how two distinct entities or groups are related.
For example, the ratio of boys to girls in a class is 12: 15, whereas, the part-to-whole ratio denotes the relationship between a specific group to a whole.
For example, out of every 10 people, 5 of them like to read books. Therefore, the part to the whole ratio is 5: 10, which means every 5 people from 10 people like to read books.
Let us assume price of radios are x and y
According to the question
[tex]\frac{x + 20}{y+20} =\frac{5}{2}\\2x+40=5y+100\\2x-5y=60[/tex]-------------------------- eq(1)

Finding the multiplier to give a final amount after a percentage increase or decrease
With percent increase or decrease situations, you have to consider the starting point as being 100%. So if the account increased by 27%, it's now 100% + 27% or 127% of it's original value.
As a decimal, 127% = 1.27. So 1.27 is your multiplier in this example.
And 1.27 • 7600 = 9652, which is the ending balance.
This gets the same result as finding 27% of 7600 and adding it back on to 7600, but does it more efficiently.
