Answer: a = 65° b = 78° c = 37°
Steps:
(2x - 9) + (2x + 4) + x = 180°
5x - 5 = 180 °
5x = 185°
x = 37
(2x + 4)
2(37) + 4
74 + 4 = 78
(2x - 9)
2(37) - 9
74 - 9 = 65
Check:
65° + 78° + 37° = 180°
180° = 180°
Answer:
x: $20 an hour independent variable

It is A.) because circumference = 50.27
Answer:
<h2>S.A. = 66m²</h2>
Step-by-step explanation:
Look at the picture.
We have :
4 rectangles 3m × 4m → A₁ = 3 · 4 = 12 m²
2 rectangles 3m × 3m → A₂ = 3 · 3 = 9 m²
Therefore the Surface Area of the rectangular prism is:
S.A. = 4A₁ + 2A₂
Substitute:
S.A. = 4(12) + 2(9) = 48 + 18 = 66
