Question

If a ll b and e ll f, what is the value of y?
-87
-88
-91
-92

Answer 1

92

Explanation:

Angle (x+1) is equal to 92 degrees, and x equals 91. If x equals 91, then (x+1) equals 92. (x+1) and angle y are equal angles, so therefore, you can determine that angle y is equal to 92 degrees.

Hope this helps!

Answer 2

e || f, so

x+1+x-3=180

2x=182

x=91

91-3=88

a || b, so

y+88=180

y=92

Answer: 92
