Answer:

3) m∡ACB = 40 m∡ABC = 63

4) m∡BCA = 14 m∡ABC = 83

Step-by-step explanation:

Since DE is a line it has 180 degrees so:

103 + CAB = 180

CAB = 77 degrees

All triangle interior angles of a triangle add up to 180 degrees, so:

BAC + ACB + CBA = 180

3x - 14 + 3x + 9 + 77 = 180

6x + 72 = 180

6x = 108

x = 18

Plug in your values:

3(18) - 14 = 40

3(18) + 9 = 63

Use the same method for the next problem.
