X = smallest; x + 2 = middle, and x + 4 = largest
x + 2(x+2) = 20 + x + 4
x + 2x + 4=24 +x
3x + 4 = 24 + x
2x = 20
x = 10
so the three integers are 10, 12, and 14
Answer:
27.7 cm
Step-by-step explanation:
The cosine of an angle is the ratio of the adjacent side in a right triangle to the hypotenuse. Here, that means ...
cos(30°) = y/(32 cm)
y = cos(30°)·(32 cm) ≈ 0.866·(32 cm)
y ≈ 27.7 cm
