Question

Can someone help and can you also put the reason why it is the answer?

Answer 1

5 c = 45 , d = 97

Explanation:

5) You know the entire triangle has a total of 180 degrees, you also know that angle c + 135 has to equal 180.

So for angle C, you will set up your formula c=180-135 = 45

Now you set up your formula for angle d.

180=angle c + angle d +38

180 = 45 + D + 38 -> D = 180-45-38 = 97
