Question

I need help to find X = in decimal form

Answer 1

Answer: x=11.4

Step-by-step explanation:

Since we have similar figures, we can use ratios to solve for x. To step up the ratios, we want the value on one side of the triangle to match up with the other value on the same side of another triangle.

x = 15

-- --

3.8 5

Next, we cross multiply the values.

x(5)=15(3.8)

5x=57

Then, divide 5 from both sides.

5x/5=57/5

x=11.4

Answer 2

x = 11.4

Explanation:

Since the triangles are similar, we can use ratios to find

x 15

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

3.8 5

Using cross products

5x = 3.8(15)

5x=57

Divide by 5

5x/5 = 57/5

x=11.4
