The angles are supplementary so they add up to 180 degrees. The equation would be
x + 3x + 54 = 180
4x = 180-54
4x = 126
x = 31.5 degrees
1st angle is 31.5 degrees
2nd angle is 3x+54 = 148.5 degrees.
To check 148.5+31.5 = 180
Answer:
Step-by-step explanation:
4 and a half
Answer: a- 10x^2 + 3x - 4
The answer is 72$
it is really closest to 72 it is 70.12222220
Step-by-step explanation:
normally there are 6 surface areas on a prism (or simply "box").
for the lateral surface area we ignore the indicated (shaded) areas as to and bottom. that leaves us with the 4 white ones.
so, we have 2 rectangles of 4×3 and 2 rectangles (the missing side lengths must be identical to the other specified lengths given the graphic, otherwise the sides would not fit together to build the prism) of 1.5×4.
the total lateral surface area is therefore
2×3×4 + 2×1.5×4 = 24 + 12 = 36 ft²
