Question

Find x on the triangle

Answer 1

Answer:

Ans = 5

Step-by-step explanation:

We notice that the 2 triangles are congruent.

We also notice that one of the side of the bigger triangle is 4 times greater than the side of the other smaller triangle.

We have already stated that they are congruent.

Therefore, the side lengths should be in proportion.

1st side- 3(side of smaller triangle) * 4 = 12(side of bigger triangle)

2nd side- x(side of smaller triangle) * 4 = 20(side of bigger triangle)

4x = 20

x = 20/4  = 5

Therfore the required side has length 5
