Question

6) Which variable equals 55?

7) Which variable equals 101?

Answer 1

5) ?

6) y = 55

7) no variable equals 101 in this triangle

Explanation:

5) There was no question for 5

6) This is the answer because:

x = 79: 65+36+x = 180, 101+x = 180, x = 79

z = 144: 180 - 36 = 44

y = 55: 36+79+(y+10) = 180, 115+(y+10) = 180, y+10 = 65, y = 55

Hope this helps!
