Answer:

angle XZY=80+62+x=180,

80+62=142,

since a triangle adds upto 180,

Answ,,180-142=38

Answer:

YES.

Step-by-step explanation:

4x + 12 = 180 - 80

4x + 12 = 100

4x = 88

x = 22.

So m <ACB = 180 - (8(22)-34)

= 180 - 142 = 38 degrees.

so m <BAC =  180 - 80 - 38 = 62 degrees.

So the 3 angles in triangle ABC ( 80, 62 and 38) are equal to the 3 angles in triangle XYZ.

So they are similar.
