Find m∠aeb
a 10
b 70
c 110
d 170

A. 10

Step-by-step explanation:

The two angles are vertical angles, thus they are equal. You solve once you set the two angles equal in an equation. See work for more.

50%

Step-by-step explanation:

If 480 = 100%, then we simply find how far 480 and 240 are apart.

Since we know that 240 is half of 480, it is the same as 100 divided by 2.

Which happens to be a exact 1/2 of 100. Or "50".

So now we have 50%, which is the answer!
