Find the missing angles... both 4 and 5 separately

4 : 34

5 : 102

Step-by-step explanation:

This problem can be solved by using concept of co-interior angles.

co interior angles are those angles which lie on the same of parallel lines when the parallel lines are cut by transversal.

sum of co interior angles is 180 degrees.

In the problem 4 and 5 then angle given and missing angles are co-interior angles.

Problem 4

146 + ? = 180

? = 180 -146 = 34

Thus missing  angle in problem 4 is 34 degrees

Problem 5

78 + ? = 180

? = 180 -78 = 102

Thus missing  angle in problem 5 is 102 degrees

true
