Answer:
-4
Step-by-step explanation:
Two legs of the triangle are congruent as shown by the tick marks. This means that this is an isosceles triangle; in an isosceles triangle, the two base angles are also congruent. Which means <A and <B are congruent.
So to solve for x, set 28 and 10x+68 equal to each other.
28=10x+68
First, subtract 68 from both sides
-40=10x
Then, divide both sides by 10
-4=x
If you want to check your answer plug -4 back into the original equation.
28=10(-4)+68
28=-40+68
28=28, which is true, therefore -4 is correct.
