Find the length of side a in the right triangle below. 17
a
15
The length of the side, a, is approximately

I'm assuming that a is the hypotenuse (Longest side)

Step-by-step explanation:

22.67 is the answer

If a isn't the hypotenuse (Longest side) then let me know in the comments then I will comment the right answer for you <3

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
