Answer 1

Answer:

45°

Step-by-step explanation:

according to the question,

a=3b

the line is a straight line which equals to 180°

then,

a+b=180°

3b+b=180°

4b=180°

b= 180/4

b= 45°

Answer 2

Step-by-step explanation:

Now,

angle 1+angle 2=180°(supplementary angle

a+b=180°

3b+b =180°

4b=180°

b=180/4

b=45°

if b=45° then ,

a=3b

a=3×45

a=135°
