Answer:
Angle A: 72°
Angle B: 108°
Step-by-step explanation:
Opposite angles are equal
Adjacent angles add up to 180
5y - 3 = 3y + 27
2y = 30
y = 15
Angle A:
5(15) - 3 = 72°
Angle B:
180 - 72 = 108°

Answer:
cone: 138.16 in²
pyramid: 352 m²
Step-by-step explanation:
Use the appropriate formula from your list of area and volume formulas.
<u>Area of a Cone</u>
A = πr(r +h) . . . . . where r is the radius and h is the slant height
The radius is half the diameter, so is 4 inches.
A = π(4 in)(4 in + 7 in) = 44π in² ≈ 138.16 in²
__
<u>Lateral Area of a Square Pyramid</u>
A = 2sh . . . . . where s is the side length of the base and h is the slant height
A = 2(8 m)(22 m) = 352 m²
Answer:
H
