$x = 20^{\circ}$

$\angle A = 150^{\circ}$

Step-by-step explanation:

Given

$\angle A = 8x - 10$

$\angle B = 3x + 90$

See attachment

From the attachment A and B are vertically opposite.

This implies that:

$\angle A = \angle B$

Substitute values for A and B

8x - 10 = 3x + 90

Collect Like Terms

8x - 3x = 10 + 90

5x = 100

Solve for x

$x = \frac{100}{5}$

$x = 20^{\circ}$

Substitute 20 for x in $\angle A = 8x - 10$

$\angle A = 8 * 20 - 10$

$\angle A = 150^{\circ}$

1/2 mile

Step-by-step explanation:

If you add 1/4 and 1 3/4, you get 2. Then, subtract 2 1/2-2=1/2
