Question

Find the value of x please help

Answer 1

Answer:

6

Step-by-step explanation:

Find the ratio between the two triangles:

x is parallel to side 9

10 is parallel to an unknown quantity (Which is 15 if you need that later)

8 is parallel to side 12

Considering we only have known quantities with 8 and 12, we will use those.

12÷8 = 1.5

Therefore, the ratio between the two triangles is 1.5

Since we know the bigger length of the triangle, we will divide to get an obviously smaller quantity.

9÷1.5 = x

x=6

or,

You can find the hypotenuse (even though that's obviously not what the lesson is but why not?).

a²+b² = c² is the formula.

x²+8² = 10²

x²+ 64 = 100

x² = 36

√36 = 6

So, x is equal to 6.

Hope this helps!
