how to construct an angle bisector of a given angle.
how to use an angle bisector to construct some angles for example, 90 degrees, 45 degrees, 60 degrees, 30 degrees, 120 degrees, 135 degrees, 15 degrees.
An angle bisector is a straight line that divides the angle into two equal parts.
Example: Construct an angle bisector for the following angle:
Solution:
Step 1 : Put the sharp end of your compasses at point B and make one arc on the line BC (point S) and another arc on line AB (point T).
Step 2 : Put the sharp end of the compasses at S and make an arc within the lines AB and BC. Do the same at T and make sure that the second arc intersects the first arc.
construct angle bisector
Step 3 : Draw a line from point B to the points of intersection of the 2 arcs. This line bisects ∠ABC.
construct angle bisector
The steps to construct an angle bisector can be summarized as follows:
1. From the vertex, draw an arc across both rays of the angle.
2. From each arc intersection draw another pair of arcs that intersect each other.
3. Draw a line from the vertex to the intersection point to form the angle bisector.

Rearrange this formula to make x the subject.
y = 3x2 - 2
Answer:
The subject 'x' in terms of 'y'
[tex]x = \sqrt{\frac{y+2}{3} }[/tex]
Step-by-step explanation:
Explanation:-
Given subject in terms of 'x'
y = 3 x² - 2
Adding '2' on both sides, we get
y + 2 = 3 x² - 2 +2
y+2 = 3 x²
Dividing '3' on both sides, we get
[tex]x^{2} = \frac{y+2}{3}[/tex]
[tex]x = \sqrt{\frac{y+2}{3} }[/tex]
-2(4x-1)-7=5
whats the next step in solving this equation
Answer:
Using distributive property is the next step in solving the equation
Step-by-step explanation:
-2(4x-1)-7=5
-8x+2-7=5
Answer:
The next step would be to do distributive property.
Step-by-step explanation:
-2(4x-1)-7=5
-8x + 2 - 7 = 5
-8x - 5 = 5
+5 +5
-8x = 10
/-8 /-8
x= -5/4
or
x = -1 1/4

In 1971, the average price of gasoline was $0.36 per gallon. In 2020, the average price of gasoline was $2.32 per gallon. a. What is the percent increase, rounded to the nearest whole number, in the cost of a gallon of gasoline from 1971 to 2020? b. What is the percent decrease, rounded to the nearest whole number, in the cost of a gallon of gasoline from 2020 to 1971? 2. Last year, DeKalb Middle School had 140 7 thgraders. The number of 8 thgraders was 125% of the number of 7 thgraders. How many 8 thgraders were there last year? 3. Find the balance of a savings account at the end of 4 years if the interest earned each year is 5.5%. The principal is $700.
Answer:
1. a. 544%
b. 84%
2. 175
3. $867.18
Step-by-step explanation:
1. a.2.32-0.36=1.96
1.96/0.36=5.44
5.44*100=544
b. 1.96/2.32=0.84
0.84*100=84
2. let x = # of 7th graders
let y = # of 8th graders
y is 125% of x
y=1.25x
x=140
y=1.25*140
y=175
3. A=P(1+r)^t
A=700(1+0.055)^4
A=867.18

Four positive whole numbers add up to 96
One of the numbers is a multiple of 19
The other three numbers are equal.
What are the four

Multiple of 19
goes here
Other four Positive whole number is 13
What is whole number?The whole numbers are the numbers without fractions and it is a collection of positive integers and zero. It is represented by the symbol “W” and the set of numbers are {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,……………}. Zero as a whole represents nothing or a null value.
According to the question
First, we consider that if we add together three equal numbers, the result must be a multiple of three. For example, 7 + 7 + 7 = 21, or 11 + 11 + 11 = 33.
Algebraically, we'd say that n + n + n = 3n.
So this means that if we subtract the first number (the one that's a multiple of 19) from 97, we will have a result that is a multiple of 3.
What could the first number be? 19, 38, 57 or 76 . Any other value is larger than the sum of 7, which is not possible if all the integers are non-negative.
Based on this, we can find all possible sums of the other four numbers, by subtracting each of the numbers above from 96:
96 - 19 = 77
96 - 38 = 58
96 - 57 = 39
96 - 76 = 20
Remember what I said earlier? The other four numbers must add to a multiple of 3. The only one of those sums above that is a multiple of 3 is 39. Therefore, we conclude that the first number is 57, and the other four numbers are each 13 (because 39 / 3 = 13).
Hence, other four number is 13

Find the measure of angle b
Answer:
26˚
Step-by-step explanation:
Since there is already two angles (The square in the corner shows that the angle is 90˚)
So subtract 90˚ with 64˚ which is 26˚
Answer:
this whole angle is equal to 90°
so the value of angle b = 90°-64°
so the value of b= 26.
