please tell me the angle of elevation
Answer:
32°
Step-by-step explanation:
The model forms a triangle. The sum of the angles of a triangle is 180°. Solve with the following equation:
? + 90 + 58 = 180
? + 148 = 180
? = 32
Therefore, the angle of elevation is 32°.

Measure of angle 1 from the given circle is 40 degree. Therefore, option B is the correct answer.
What is secant tangent rule?If a line is drawn from an external point to a circle, creating a tangent segment and a secant segment, then the length of the tangent segment squared is equal to the product of the lengths of the secant segment and its external segment.
Given that, PB is tangent and PV and PU are secant.
Here, measure of arc VU = 80° and measure of arc ST = 30°
Now, m∠1=1/2 ×measure of arc VU
m∠1=1/2 ×80°
m∠1=40°
Therefore, option B is the correct answer.

-5f - 8=2(3f+2)
---------------
Answer:
f = - [tex]\frac{12}{11}[/tex]
Step-by-step explanation:
Given
- 5f - 8 = 2(3f + 2) ← distribute parenthesis
- 5f - 8 = 6f + 4 ( subtract 6f from both sides )
- 11f - 8 = 4 ( add 8 to both sides )
- 11f = 12 ( divide both sides by - 11 )
f = [tex]\frac{12}{-11}[/tex] = - [tex]\frac{12}{11}[/tex]
Answer:
f= -12/11
Step-by-step explanation:
-5f-8=6f+4

-8=11f+4

-12=11f

Is 8.888... a rational number?
=================================================
Explanation:
Since the decimal repeats itself infinitely (the 8s go on forever), this is one sign that we have a rational number.
Rational numbers always have some kind of infinitely repeating pattern when we convert them to decimal form.
---------------------
Extra info (optional section)
If you want to determine what this number is equal to, then let's say that
x = 8.8888...
Multiplying both sides by 10 gets us
10x = 88.888....
Now we'll subtract the two equations
The 10x-x becomes 9x while the 88.8888...-8.8888... turns into 80
We're left with 9x = 80 which solves to x = 80/9
Therefore, 80/9 = 8.8888.... showing that we have a rational number
Any rational number is basically a fraction of two whole numbers.
Solve 2x−10y=18 for x.
Answer:
x = 5y + 9
Step-by-step explanation:
2x - 10y = 18
(2x - 10y) + 10y = 18 + 10y
2x - 10y + 10y = 10y + 18
2x = 10y + 18
x = 5y + 9
The dimensions of four rectangles are given below. Which has an area different from the area of each of the other three?
To determine which of the rectangles has a different area, the areas of the four rectangles must be calculated. The rectangle with a different area is rectangle b
The dimension of the 4 rectangles are:
a. length: 4x and width: 4
b. length: 11 and width: x
c. length: 2 and width: 8x
d. length: 16x and width: 1
The area of a rectangle is:
[tex]Area = Length \times Width[/tex]
Rectangle (a)
[tex]Area = 4x \times 4[/tex]
[tex]Area = 16x[/tex]
Rectangle (b)
[tex]Area = 11 \times x[/tex]
[tex]Area = 11x[/tex]
Rectangle (c)
[tex]Area = 2 \times 8x[/tex]
[tex]Area = 16x[/tex]
Rectangle (d)
[tex]Area = 16x \times 1[/tex]
[tex]Area = 16x[/tex]
Rectangles (a), (c) and (d) have the same area (i.e. 16x) while rectangle (b) has 11x as its area.
Hence, the rectangle with a different area is rectangle (b).
