Answer:
1058.4 in^2
Step-by-step explanation:
Find the surface areas of the rectangular prism and the triangular prisms separately.
Triangular: S = (1/2)lP+B, where l is slant height, P perimeter, and B base area.
14(4)= 56 perimeter of base
13 slant height
B = 14x14 = 196
put together:
S = (1/2)(13 x 56) + 196
S = 560 in^2
Now the rectangular prism
S = 2lw + 2lh + 2wh, where l is length, h height, w width. (delete the first 2lw since they share one side/they're combined shapes.
S = 2(14x8.9) + 2(14x8.9)
S = 498.4 in^2
Add them together: 498.4 + 560 = 1058.4 in^2
Answer: 135*
Step-by-step explanation:
35* is what the bottom left side of the triangle angle equals because of congruency.
All triangles = 180*
180 - 100 - 35 = 45*
top angle of triangle = 45 *
said angle (45) + x angle = 180
x = 135*

Step-by-step explanation:
The answer is b. There is a proof, but it is easily got by proving the other cases wrong.
