Question

Find the size of each of the unknown angles
plz give me solution​

Answer 1

Firstly, draw a line parallel to UT

Something like in the picture

Now,

a = BNU

Also,

BNU + BNM = 165°

Answer 2

• 80°

Explanation:

See the picture

It should be self-explanatory

The top part of the angle a is:

• 35° + 165° - 180° = 20°

The bottom part of the angle a is:

• 180° - 120° = 60°

The measure of angle a is:

• 20° + 60° = 80°
