PLEASE HELP, WILL GIVE LOTS OF POINTS &br /> solve the 2 questions!

5) we get a=6

6) we get c=8

Step-by-step explanation:

The triangles given are similar.

When the triangles are similar, the ratio of corresponding sides are also similar.

5) If c = 12, find a

We will use the ratio

Now cross multiply to find value of a

So, we get a=6

6. If b = 6.4, find c

We will use the ratio

Now cross multiply to find value of b

So, we get c=8

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

positive

step-by-step explanation:

the quadrant is facing upwards
