Question

In the figure, m∠4 = 74° and m∠3 = 43°.
Find the measures of ∠1 and ∠2.​

Answer 1

Answer:

Angle 2 is 106°

Angle 1 is 31°

Step-by-step explanation:

180 - 74 = 106 (Angle 2)

106 + 43 = 149

180 - 149 = 31 (Angle 1)

Answer 2

Angle 1= 31
Angle 2= 106
Angles 2 & 4 will add up to 180 deg. As supplementary angles.
Interior angles of triangle will equal 180 deg.
