Answer:
Step-by-step explanation:
Triangle ABC is a right angle triangle.
From the given right angle triangle
AB represents the hypotenuse of the right angle triangle.
With m∠A as the reference angle,
AC represents the adjacent side of the right angle triangle.
BC represents the opposite side of the right angle triangle.
To determine AB, we would apply the Cosine trigonometric ratio
Cos θ = opposite side/hypotenuse. Therefore,
Cos 52 = 10/AB
0.616 = 10/AB
AB = 10/0.616
AB = 16.23
Answer:
336 ft²
Step-by-step explanation:
The rectangle is 13 ft long and 8 width that means we have two walls 8* 9 and two walls 13*9
Total walls area is
2*8*9 + 2*13*9 = 144 + 234 = 378 ft²
then we subtrac , areas of door, closet and windows
3 * 6.5 = 19,5 ft²
3 * 6,5 = 19,5 ft²
2 * 1,5 = 3 ft²
42 ft²
Then area to paint 378 - 42 = 336 ft²
it would be 66 cause you know it
