Which proportion could be used to find the length of side b?

Mathematics
1 answer:
UNO [17]2 years ago
6 0

Answer:

A

Step-by-step explanation:

\frac{sin A}{a} = \frac{sin B}{b}  = \frac{sin C}{c}

Also, you need to subtract the 2 known angles from 180 to find the missing angle measurement. 180 - 85 - 64 = 31

The angles go with the side lengths opposite them.

\frac{sin 64}{a}  = \frac{sin 85}{b} = \frac{sin 31}{9.3}

A spheres radius is multiplied by 2. How is it’s surface area affected
dexar [7]

Answer:

The surface area is multiplied by 3.

Step-by-step explanation:

If r is the radius of a sphere its surface area = 4(pi)r^2. If the radius is doubled then its surface area = 4(pi)(2r)^2 = 4*4(pi)r^2. So the surface area becomes 4-fold or the increase in surface area is 300%.
