Question

Find the measure of the third angle of a triangle

a) ∠P=60, ∠Q=60

b) ∠L=70, ∠M=80

c)∠X= 90, ∠Y=10

​

Answer 1

Answer:

a) 60

b) 30

c) 80

Step-by-step explanation:

a) 60+60+x=180

=120+x=180

=x=180-120

x=60°

b) 70+80+x=180

=150+x=180

=x=180-150

x=30°

c) 90+10+x=180

=100+x=180

=x=180-100

x=80°
