An isosceles triangle has angles with ratios 1:2:2. What is the measurement of the angle within the triangle with ratio 2?  Choose the correct answer.
A) 36Â°
B) 46Â°
C) 72Â°
D) 92Â°
E) 100Â°
Given that the ratio is 1:2:2 and that the total angle measurement within a triangle is 180Â°, the equation is   1x + 2x + 2x = 180Â°   5x = 180Â°   x = 36Â°   But since we want to find the angle measurement with ratio 2, we multiple x by 2   2x = 2(36Â°) = 72Â°   Therefore, the answer is 72Â° or 72Â°.
