Question

Help me please thank you

Answer 1

AFB is acute. DFB is obtuse. Finally CFD is right. And those are the"right answers" and your welcome hope you get a 100%

Answer 2

AFB = 48 degrees

DFB = 138 degrees

CFD = 90 degrees

In order to find AFB, we can see that AFC is equal to 90. We then subtract the 42 degree angle on the inside of it.

90 - 42 = 48

For the DFB angle, we know that we have a 90 degree angle plus the 42 degree angle. So we add them together.

90 + 42 = 132

Lastly CFD is a right angle and therefore is equal to 90.
