Question

Triangle MAT is isosceles, angle A is the vertex angle, AT = 8x-3, MT = 2x+3 and MA=5x+15. Find the value of x and the indicated measures.

Please solve step by step to help me understand. Thanks!

Answer 1

x=6, AT=45, MT=15, MA=45

Explanation:

Because it is isosceles, MA=AT, so 8x-3=5x+15, solve for x and then plug it into the equations.
