Please help me find the value of x the answer must be exact

Step-by-step explanation:

This is a 45°-45°-90° triangle. The two legs are the same length, and the hypotenuse is that length times the square root of two:

Therefore, the value of x is 11.

You can double-check using the sine ratio:

Insert the values:

Insert the equation into a calculator:

:Done

*It's important to know that, when working with trigonometry ratios, the hypotenuse is never considered the adjacent or opposite side, and the 90° angle is never used in the ratios.

x/7.50 = 15

x= 7.50 / 15 divide

step-by-step explanation:

y=mx+b is the final answer!   : )
