Hi there!

$\large\boxed{\text{ sum = 180(n - 2)}}$

This is the formula for finding the sum of interior angles for a polygon with a number of sides "n".

We can also prove this from the table:

Triangle ⇒ 3 sides: 180(3 - 2) = 180°

Quadrilateral ⇒ 4 sides: 180(4 - 2) = 360°

Pentagon ⇒ 5 sides: 180(5 - 2) = 540°

...And so forth. We can write this as for any polygon with "n" sides:

180(n - 2) = sum (°)

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:

$B = C$

$C = 102^\circ$
