Question

Solve for the value of e.

Answer 1

e=62

Explanation:

`49 + 2e + 7 = 180degree \\ 56 + 2e = 180 \\ 2e = 180 - 56 \\ 2e = 124 \\ e = 124 / 2 \\ e = 64`

Answer 2

69

Explanation:

1. 180-49=131 (supplementary angle)

2. 2e-7=131 (solve for e)

3. 2e=138 (add to rhs to remove -7)

4. 2e/2 = 138/2 (divide rhs to remove x2)

5. E= 69 (138\2
