Answer:
x ≈ 38.7°
Step-by-step explanation:
Using the sine ratio in the right triangle
sinx = 
= 
, then
x = 
( ) ≈ 38.7° ( to 1 dec. place )
(<span>5a-5)(2a+2)
= 5a*2a -5*2a + 2*5a - 5*2
= 10a^2 - 10a + 10a - 10
= 10a^2 - 10
The product of the equation is </span>10a^2 - 10
The answer would be 30in.
Reasoning: if the two figures are proportional, you would set it up in a proportion. It would be 36/x=12/10. Then cross multiply, so it would be 12x and 36(10). Afterwords you’ll have 12x=360, then divide both sides by 12 and you’ll end up with 30.
The answer is C, 135. To find the solution, first find the area of the closet by multiplying 3 by 5, which is 15. Then, find the area of the entire room by multiplying 15 by 10 to get 150. Finally, subtract 15 from 150 to find the solution of 135 square feet.
