Answer:
5 c = 45 , d = 97
Step-by-step 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
