Answer: x = 17
Step-by-step explanation:
2+x = 2x-15
subtract x on both sides
2 = x -15
add 15 to both sides

------------------
17+2 = 2(17)-15
19 = 34 -15
19 = 19
SSS theorem: If two triangles have three pairs of sides in the same ratio, then the triangles are similar.
Write the ratio between the smallest sides, between the greatest sides and between the middle sides and compare the results:



This gives you that
