I will give who ever answers this brainliest but it has to be right

10 -

c = 5.1

a = 3.1

11 -

Step-by-step explanation:

10 -

3.7 / 3 = 1.2333    You need this to find how much greater the left side is.

c = 4.1 x 1.2333

a = 2.5 x 1.2333

11 -

y=15

z=

(If two triangles are next to each other with a straight line and one is a right angle, so is the other triangle)

Since they are both right angles, they are 3,4,5 triangles.

The 12 would count as the four since is divides by 4

The y would equal 15 because it is the longest side meaning it has to be the  5. Since we had to divide the 12 by 3 to get the four, we have to multiply the 5 by 3 to get 15.

Now to find z, you will make the equation 15/12=z/5
