Answer:
y=5x-21
Step-by-step explanation:
Note that this is a vertical angle, and so the angles will be congruent. Set the measurements equal to each other, isolate the x, and solve for x:
3x + 20 = 5x - 16
First, subtract 5x from both sides, and 20 from both sides
3x (-5x) + 20 (-20) = 5x (-5x) - 16 (-20)
3x - 5x = -16 - 20
Simplify. Combine like terms
-2x = -36
Isolate the x. Divide -2 from both sides
(-2x)/-2 = (-36)/-2
x = (-36)/-2
x = 18
18 is your answer for x

Answer: 258.31 cm²
<u>Here it's given that ,</u>
- Circumference of the circle = 57cm.
<u>To Find ,</u>
We know that ,
→ Circumference = 2πr
Substituting the respective value ,
→ 57cm = 2πr
→ r = 57cm/2π
→ r = 57/(2*3.14) cm
→ r = 9.07 cm
And ,
→ Area = πr²
→ Area = 3.14 * (9.07cm)²
→ Area = 3.14 * 82.26 cm²
→ Area = 258.31 cm²
<u>Hence</u><u> the</u><u> </u><u>area</u><u> of</u><u> the</u><u> circle</u><u> is</u><u> </u><u>2</u><u>5</u><u>8</u><u>.</u><u>3</u><u>1</u><u> </u><u>cm²</u>
