GEOMETRY HELP WILL MARK BRAINLIEST
klasskru [66]

Answer:

X = 2 / Z = 78

Explanation:

We are given 102 degrees, and the formula across from it, the one with the x, equals the same degrees. Knowing that we have to get them to equal each other, subtract 102-86, and you'll get 16. Next, divide 16 by the given number, 8, and you'll get x = 2

Knowing a straight line equals 180 degrees, subtract 180-102, and you'll get z, which is 78
