X=1/2 y+6 . Hope it helps.
Formula for the area of a quarter circle: A = (pi x r^2) / 4
3.14 = (3.14 x r^2) / 4
3.14r^2 = 12.56
r^2 = 4
r = 2 meters
Hope this helps! :)
Ii.First ,expand: 5(x-2)=32
5x-10=32
bring 10 to the other side (add it to 32)
5x=42
divide both sides by 5 to get x
x=42/5
x=8.4
iii.Expand 5+2(x+3)=21
5+2x+6=21
bring 5 and 6 to the other side
2x=21-5-6
2x=10 divide both sides by 2
x=5
Answer:
x = 63.7°
Step-by-step explanation:
Since the triangle is right we can use trig. ratios to solve
tan x° =
= 
⇒ x =
(
) = 63.7°
