Question

What are the measures of ∠1, ∠2, ∠3 and∠4 ? Enter your answers in the boxes.




m∠1=____ m∠2=_____ m∠3=_____ m∠4=______

Answer 1

Step-by-step explanation:

Since line p and q is parallel, m∠2=61°.

m∠2 and m∠3 are in a straight line. thus, m∠2+m∠3 = 180°.

61° + m∠3 = 180°

m∠3 = 119°

total angle in triangle is 180°

m∠1 + m∠2 + 60° = 180°

m∠1 + 61° + 60° = 180°

m∠1 = 59°

m∠1 = m∠4 = 59°
