Find the degree measure of the angle EFK if: 1) The angle EFN is a straight line. KFN = 55 °

Find the degree measure of the angle EFK if: 1) The angle EFN is a straight line. KFN = 55 ° 2) The PFK angle is 115 °. PFE corner – straight

In order to solve this problem, you need to find the degree measure of the angle EFK:

1) The right angle is 90 °.

2) In the first example, the angle EFK is equal to the sum of the angle EFN and KFN: 90 ° + 55 ° = 145 °.

3) In the second example, the angle EFK is equal to the difference between the angle PFK and PFE: 115 ° – 90 ° = 25 °.

Therefore our answer is 145 ° and 25 °.
