Find x (btw if you answer randomly to just get point imma report ur acc)

x=3

Step-by-step explanation:

the triangles are similar, set their congruent parts equal to one another (4/x=10/7.5). Cross multiply. Simplify.

remember to add 4 and 6 to get the full length of the larger triangle's side.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
