Answer:

Step-by-step explanation:
Firstly we've to find the hypotenuse of the first triangle:
<u>In the first triangle, for the angle 45: </u>
Adjacent = 10
Hypotenuse = ?
Using cos for it.
Cos 45 = adjacent / hypotenuse
0.707 = 10 / hyp
hyp = 10 / 0.707
hyp = 14.14
The hypotenuse of the first triangle is actually the base (or opposite) of the triangle.
Also, hypotenuse = x and angle is 60 degrees.
<u>So, we will use the sin ratio.</u>
sin 60 = opposite / hypotenuse
0.866 = 14.14 / x
x = 14.14 / 0.866
x = 16.3
