Question 852595
Three angles; A, B, C
:
Write an equation for each statement
:
The measure of the second angle of a triangle is 50 more than that of the first angle.
B = A + 50
 The measure of the third angle is 10 less than twice the first angle.
C = A - 10
:
Find the measures of the angles.
We know
A + B + C = 180
Replace B with (A+50) and C with (A-10) and find A
