A pair of congruent angles are described as follows: The measure of one angle is three more than twice a number (x), and the other angles measure is 54.5 less than three times x

The measure of one angle is three more than twice a number (x), and the other angles measure is 54.5 less than three times x

 

 

[2x + 3] + [3x - 54.5]  = 90    simplify

 

5x -51.5 = 90      add 51.5 to both sides

 

5x  = 141.5      divide both sides by 5

 

x = abput 28.3°

 

So the first angle = 2(28.3) + 3 =  59.6°

 

And the second angle = 3(28.3) - 54.5  = 30.4°

 

 

 

cool cool cool
