m∠1=42°

Step-by-step explanation

For this problem, we can separate the triangle into 2 separate triangles to solve for m∠1.

We know that m∠4 is 106°. ∠2 and ∠4 are supplementary angles. You can see that they make a straight line of 180°. We can use this fo find ∠2.

∠2+∠4=180

∠2+106=180

∠2=74°

Now that we know ∠2 is 74°, we can use that to solve for m∠1.

We know that the measures of the angles in a triangle equal to 180°. For the triangle at the bottom, we see ∠3, ∠2, ∠1. Since we know ∠3 and ∠2, we can find ∠1.

∠3+∠2+∠1=180

64+74+∠1=180

138+∠1=180

∠1=42°
