Someone please help me with this question

x=3.5

Step-by-step explanation:

You can find x by finding the hypotenuse of that triangle, which is the leg of the other triangle. Find the value of the leg first:

You can use the sine ratio to find the leg. This is because  and we have the hypotenuse for that triangle and we need to find the side opposite the given angle, 45°. Insert values:

Solve for x. Multiply both sides by 7:

Enter the value into a calculator:

The leg is 4.9. Use this to solve for the next x. Use the sine ratio for the same reason. Insert values:

Solve for x. Multiply both sides by 4.9:

Insert into a calculator:

Finito.

yes.. it's proven to be 36.
