Answer:
x = 14
Step-by-step explanation:
The triangle has 2 congruent legs and is isosceles with 2 base angles being congruent , then
5x = 3x + 28 ( subtract 3x from both sides )
2x = 28 ( divide both sides by 2 )
x = 14
First way is create an equation like this:
and calculating it.
Second way is to find 37% of each number and then add it

+

In both cases the result is 10.829
