<u>Part a) What is the value of a?</u>

we know that

m∠a=63\° -------> by corresponding angles

therefore

<u>the answer part a) is </u>

m∠a=63\°

<u>Part b) What is the value of h?</u>

we know that

m∠h+120\°=180\° ---> by consecutive interior angles (supplementary angles)

m∠h=180\°-120\°

m∠h=60\°

therefore

<u>the answer part b) is</u>

m∠h=60\°

<u>Part c) What is the value of b?</u>

we know that

m∠b=128\° -------> by alternate interior angles

therefore

<u>the answer part c) is </u>

m∠b=128\°

The answer to solve these problems is that the full circle is 360 degrees, the way to find the answer is to have to equal sides that equal 360 degrees. That means one half of 360 degrees is 180 degrees. Hope this helps.
