The first angle of a triangle is 13 degrees more than the second angle the third angle of a triangle is 2 times the second angle use x to represent the unknown value write an algebraic expression for each of the quantities being compared what is the first angle the second angle and the third angle

Answer :

Second angle = x
First angle = 2x
Third angle = x + 68
x + 2x + (x + 68) = 180
4x + 68 = 180
4x = 112

x = 28.
First angle = 56 degrees
Second angle = 28 degrees
Third angle = 96 degrees
Total = 180 degrees.
