Answer:

m∠B=22°

Step-by-step explanation:

All angles in a triangle add up to 180 degrees

Knowing this, we now understand:

∠A+∠B+∠C=180°

Let's substitute!

(120)+(x+16)+(x)=180

120+x+16+x=180

136+2x=180

2x=44

x=22°

Let's check to make sure!

Substitute:

120+(22)+16+(22)=180

180=180

Hope this helps! :D

Good luck on your assignment :)
