Http://prntscr.com/lkz30r<br> What is the value of x?<br> 28<br> 20<br> 36<br> 17
ivolga24 [154]

This is a question that can be solved with Pythagorean Theorem since it is a right triangle. The longest side, 29, is the hypotenuse and the sides 21 and x are the legs. So, the Pythagorean Theorem states,

c^{2}= a^{2}+ b^{2}

Where,

c is the Hypotenuse, a and b are the legs. Putting the respective values gives us,

(29)^{2}= (21)^{2} +x^{2} \\841=441+x^{2} \\400=x^{2} \\20=x

So, 20 is the side length of x.

ANSWER: 20

loss means how much was lost in profit, so whenever you see that make sure to add it to whatever is applicable, like in this case, $2,640.
