The measures of two base angles of an isosceles trapezoid are 7x – 12 and 5x + 6. What is the measure of x?
Select one:
a. 3
b. 5
c. 7
d. 9


Sagot :

Because base angles on an isosceles trapezoid are equal you set up this equation
7x - 12 = 5x + 6
-5x+12    -5x +12
2x        = 18
/2            /2
x = 9
