Question

Solving simular triangles advanced

Answer 1

1.5

Explanation:

Use similar ratios. 5/4=x/6. Use cross multiplication. 30=4x. Divide by 4 to get x by itself. x=7.5 THIS IS NOT THE ANSWER!! This is the entire side length. Subtract 6 from this to get x. 7.5-6=1.5. x=1.5

Answer 2

x = 3/2

Explanation:

We can use ratios to solve

6 6+x

-------- = -----------

4 5

Using cross products

6*5 = 4 * (6+x)

30 = 24 + 4x

Subtract 24 from each side

30 -24 = 24+4x-24

6 = 4x

Divide each side by 4

6/4 = 4x/4

3/2 = x
