Find the measure of angle C in the triangle below. (The figure is not drawn to scale.)

14 degrees
28 degrees
100 degrees
52 degrees

2. Suppose a gas tank is in the shape of a cylinder. The tank is 10 feet long and 5 feet in diameter. Find the amount of metal used to construct the tank.
128.5 ft3

How man degrees are in a triangle?

Hello?

anonymous · Answer

180 I guess?

hunus · Answer

Well 100 + 2x + 4x - 4 = 180
2x+4x-4 = 100
6x = 96
x = 16

mC = 4x - 4 = 4*16 - 4 = 60

SA = 2pi*r^2 + 2pi*r*h

SA = 2*pi*2.5^2 + 2*pi*2.5*10 = 196.3

Yes, 180.

You have 1 angle given to you. So what do the other 2 angles add up to?
