I really don’t understand math and I will Mark brainliest

1.5

Step-by-step explanation:

Because the triangle are similar, they possess a proportional relationship in which the one triangle's side length is dilated by a unknown factor (y) to make its corresponding counterpart. Using this knowledge we can make the following two equations

3y=7  & xy=x+2   y is the variable representing the dilation factor

y=7/3 find the value of y

x(7/3)=x+2 substitute the value y into the equation

7/3x =x+2 solve for x

4/3x =2

(3/4)(4/3x)=2(3/4) multiply by the reciprocal

x=1.5
