In a triangle, the measure of the second angle is twice the measure of the first angle. The third angle is equal to the sum of t he other angles. Which of the following answers could represent the measures of the three angles?
A) x, 2x, 4x
B) x, 2x, 3x
C) x, 2x, 2x
2 answers:
The answer would be x,2x,3x because x is the first angle, the second angle is two times the amount (2x) and the third angle is the sum of the other two angles (x + 2x = 3x). Hope this helps.
X, 2x, and (x+2x)=3x 6x=180 x=30 30, 60, 90 triangle.
