Answer:

-3, if we assume that we only want positive square roots.

Take the (positive) square root of both 64 and 121 to get 8 and 11. 8-11= - 3.

Hope this helps :)

How to find degrees in triangle using trig?

Remember SOHCAHTOA

Sine- opposite/hypotenuse
Cosine- adjacent/hypotenuse
Tangent- opposite/adjacent

Look at the angle (x) you are trying to figure out and pick which one of these it is.

In your calculator, do the equation first to get a decimal

Then press whichever one you chose on the calculator, so if you got like 0.2 by doing opposite/adjacent for tangent, you would type in 0.2 and then the TAN button

hope this makes sense!!
