Question

2.2.2 checkup: practice problems

Answer 1

Answer:

1. 60 degrees

2. 50 degrees

4. 49 degrees

5. 26 degrees

Step-by-step explanation:

The sum of the measures of the angles of a triangle is 180 degrees.

1.

x + 80 + 40 = 180

x + 120 = 180

x = 60

2.

x + 75 + 55 = 180

x + 130 = 180

x = 50

4.

x + 90 + 41 = 180

x + 131 = 180

x = 49

5.

x + 81 + 73 = 180

x + 154 = 180

x = 26
