Answer:x = 4Step-by-step explanation:Let's look at the ratio of the hypotenuse of both triangles:25 : 5 = 25/5 = 5we can see that the measures of the sides of the larger triangle are 5 times those of the smaller triangle.Therefore, 3x + 8 = 4 x 5β 3x + 8 = 20β 3x = 20 - 8 = 12β x = 12 Γ· 3 = 4β x = 4
