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*
