Answer:
196 square feet
Step-by-step explanation:
The top and bottom faces are congruent, the front and back faces are congruent, and the left and right faces are congruent.
SA = 2(l)(w) + 2(l)(h) + 2(w)(h) = 2(10)(8) + 2(10)(1) + 2(8)(1) = 196 square feet
Answer: y = 0.5, x = 50
Step-by-step explanation: Both triangles in the picture are isosceles, telling us that the 2 angles at the bottom are congruent. With this, we can find y by doing the following:
a triangle has 180 degrees so we subtract the given 50 which gives us 130
2(2y + 64) = 130
4y + 128 = 130
y = .5
This means that the bottom 2 angles are both 65. Since the top angle of the second triangle is supplementary to the bottom angle of the first one, the top angle of the second triangle is 115. So, we find x by:
2(45 - x/4) = 65
x = 50
This means the bottom 2 angles of the second triangle are both 32.5.

➷ Use this formula:
percentage increase/decrease = (difference/original) x 100
Substitute the values in:
percentage increase = (9/30) x 100
percentage increase = 30%
