Step-by-step explanation:
30°+90°+x=180° (the sum of interior angle of a triangle is 180°)
120°+x=180°
x=180°-120°
x=60°
I think it’s 9+2 because it say sum
Ok, it is asking for the suface area of a rectangular prism - 1 base side.
So lets find the sides.
2(wl+hl+hw) l is length, w is width, h is height
wl + 2hl + 2hw is our formula
0.75 feet is 9 inches
9*(13) + 2(2)(13) + 2(9)(2)
= 117 + 53 + 36
= Your answer is 206
Please award me the brainliest if I am correct.
