Answer 1

Answer:

y = 64*, and <C and <B both equal 58*

Step-by-step explanation:

Since we know that the two sides are congruent...

3x-2 = x + 38 --> 3x = x + 40 --> 2x = 40 --> x =20.

The interior angles will all add up to equal 180.

y + (3x-2) + (x + 38) = 180

Since we know that x = 20...

y + 3(20)-2 + 20+38 = 180

y + 58+58 = 180

y+116=180

y = 64*
