Question

If m angle 9 = 119 what is the sum of the measures of angle 11 and angle 16

Answer 1

Alright lets begin. So we know that the angle 9 = 119. So the first step is finding what angle 11 and what angle 16 equal right?

Answer 2

So any angle that is open the same way as another angle means that it is equal the same value as the other angle... I know its weird. But what I am trying to say is that as we can see in the picture... angle 11 is equal to angle 9. So we know that angle 11 = 119.

Answer 3

Also, whenever an angle is diagonal to another angle it is the same value is the other angle. So since angle 16 is diagonal to angle 11 that means angle 16 is also 119.

Answer 4

So now we do 119 + 119 which is... 318! Hope that helped!
