Examine the following diagram:
Which angle is adjacent to <4?
<2
<3
<5
<8

using the formula for pythagorean theorem (a2+b2=c2)(the twos are exponents), and knowing that you have b squared and c squared, just reverse it. 26 squared minus 10 squared equals c squared. 26 squared is 676 and 10 squared is 100. you get 576, then use your square roots to undo the squared numbers to get 24.

step-by-step explanation:

i'm truly not sure if this is correct, but if you just want to simplify the equation, you would divide everything by two to get x + 6x= 16

if you want to solve-

7x=16

x= 16/7
