Answer:
x=7.5
Explanation:
Since there are 2 straight lines intersecting, the vertical angle theorem takes it.
The angle where the 2 and 5 intersect is congruent to the angle that x and 3 intersect, which means that the 2 triangles are congruent.
3/2=1.5
1.5*5(smaller triangle's hypotenuse) = 7.5
YW and sorry if i'm wrong
