Question

Find the measure of each angle

21)<1

22)<2

23)<3

24)<4

25)<5

26)<6​

Answer 1

<1) 112

<2) 68

<3) 90

<4) 90

<5) 22

<6) 158

For <4 and <2: vertical angles

For <1, <3 and <6: supplementary

For <5: since we know the measures of angles 2 and 4 and they're in a triangle with 5, when they are all added together they must equal to 180 degrees.
