Answer:
x=20, y=15 1/3
Step-by-step explanation:
The other side of the triangle is also 72 since it is an isosceles triangle. A triangle is 180 degrees. So 180-72(2)=36. Therefore, the final angle with the variable will equal 36.
(2x-4)=36
2x=40
x=20
The lines on the side mean that the two sides are congruent, or have the same measure. So you can set the expression with y in it equal to 10.
3y-36=10
3y=46
y=15 1/3
