A.)If the measure of 1 = 150°, then the measure of 6 =? B.) if the measure of 3 = 42°, then the measure of 5 = ?
C.) if the measure of 6 = 28°, then the measure of 3 =?

A.) 30

B.) 138

C.) 28

Step-by-step explanation:

A.) Angles beside each other are supplementary

180 - 150 = 30

B.) Same side interior angles are supplementary

138

C.) Opposites sides on the transversal therefore congruent

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
