Question

In figure below alb, m<1 = 78°, and m<2 = 47°.
Find measure of each angle.

Answer 1

Answer:

m∠3 =  102°

m∠4 =  102°

m∠5 =  78°

m∠6 =  133°

m∠7 =  47°

m∠8 =  47°

m∠9 =  133°

m∠10 =  102°

Step-by-step explanation:

Lines a and b are parallel and

m∠1 = 78° and

m∠2 = 47°

m∠3 = 180 - m∠1 = 180 - 78 = 102°

m∠4 = m∠3 = 102°

m∠5 = m∠1 = 78°

m∠6 = 180 - m∠7 = 180 - m∠2 = 133°

m∠7 = m∠2 = 47°

m∠8 = m∠2 = 47°

m∠9 = 180 - m∠8 = 180 - 47 = 133°

m∠10 = 180 - m∠1 = 102°
