Answer:
32
Step-by-step explanation:
area of a triangle is bxhx1/2
8x8 is 64
and then divide by 2
64/2=32
Answer:
The first angle is 37.5° and the second would be 52.5°
Step-by-step explanation:
Angles are complementary when their sums add up to 90°.
The first angle is 37.5° and the second would be 52.5°, after we plug in x.

Hi, it is very simples.
Look :
2a - 9 = -85
Pass the term -9 to the left side of equation, but changing the sinal
2a = -85 + 9
Sum -85 +9 = -76
Then,
2a = -76
Nos, pass the 2 dividing -76
a = -76 ÷ 2
a = - 38
This is the answer to the yours question
We know that
[surface area of sphere]=4πr²
[surface area of hemisphere]=2πr²
(sphere)
r=12 in
[surface area of sphere ]=4π12²--------> 576π in²
(hemisphere)
r=12 in[surface area of hemisphere ]=2π12²--------> 288π in²
[the ratio of the surface area of sphere to the surface area of hemisphere]
=576π/288π-------> 2
the answer is
the ratio is 2
