Fast! find the length of cu. the triangles are similar. show your work.

CU = 117

Step-by-step explanation:

Proportion

WC/WD = WU/WV

Givens

Solution

26/20 = (36x - 1) / 110                    Multiply both sides by 110

26 *110/20 = (36x - 1) * 110/110      Simplify

2860/20 = (36x - 1)                        Remove the brackets

143 = 36x - 1                                   Add 1 to both sides

143+1 = 36x - 1 + 1

144 = 36x                                        Divide by 36 both sides

144/36 = 36x/36

4 = x

WU = 36*x - 1

WU = 36*4 - 1

WU =  144 - 1

WU = 143

CU = WU - WC

CU = 143 - 26

CU  = 117

you answer is a

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
