Mumz [18]

Answer:

A = 78^\circ

B = 102^\circ

C = 102^\circ

Step-by-step explanation:

Given

The attached image

Required

Find A, B and C

Because the sides of the crosswalk are parallel and the sidewalks are also parallel, then the following relationships exist

A = 78^\circ ---- alternate interior angles

B = C   ---- alternate interior angles

To solve for B, we have:

B + 78 = 180 --- the sum of the base angles

B = 180 - 78

B = 102^\circ

Recall that:

B = C

C = 102^\circ

b) The answer is: (-1, -2)

The initial coordinates are:

(x, y) = (-2, -5)

Let's find a and b.

a is a distance in x direction: a = 1

b is a distance in y direction: b = 3

The final position is:

(x + a, y + b) = (-2 + 1, -5 + 3) = (-1, -2)
