Answer: x=12
Explanation:
We know that there are 2 right angles. This means that there must be a ratio involved. a/b=a/b.
In the smaller triangle, a=3, b=6, so the ratio is 3/6.
In the larger triangle, a=6, b=x, so the ratio is 6/x.
Place them equal to each other to solve.
Use the butterfly method to solve (cross-multiply).
Divide both sides by 3 to isolate the variable
There's your answer! Hope this helps :))
