18 = (240/100) x what;
what = 18 x (100/240);
what = 1800/240;
what = 7.5;
Answer:
26 percent would be your answer.
Both triangle are isosceles, which means their base angles are congruent.
54 + 2y = 180
2y = 126
y = 63
The measure of the base angles of the triangle on the left is 63 degrees.
180 - 63 = 117
117 + 2x = 180
2x = 63
x = 31.5
Answer:
x = 31.5
Hope this helps.
I’m pretty sure the answer is C. I’m not entirely sure.
