The triangles are similar.
what is the value of x?
enter your answer in the box.
x =

find the ratio:

15/3 = 5

25/5 = 5

so now 4*5 =20

 so 3x+8 = 20

3x+8 =20

subtract 8 from each side:

3x = 20-8

3x =12

 divide both sides by 3

 x = 12/3

x = 4

please mark brainliest

The value of x is 4 .

Step-by-step explanation:

As given in the question triangles are similar .

Now by using the property .

As triangle are similar than their  corresponding sides ratios are equal .

Perpendicular of the larger triangle = 3x + 8

Base of the larger triangle = 15

Perpendicular of the smaller triangle = 4

Base of the smaller triangle = 3

Putting in the above

Simplify the above

(3x + 8 ) × 3 = 15 × 4

9x + 24 = 60

9x = 60 - 24

9x = 36

x = 4

Therefore the value of x is 4 .

uhhh idk u yolo?
