Pretend the stuff under it cannot be touched when adding or subtracting
so (square root of 15) + (square root of 15) =
2(square root of 15)

Answer:
<h3>x = 49.6°</h3>
Step-by-step explanation:
Find the image attached;
From the image;
opposite side = 16
Hypotenuse = 21
Angle of inclination = x
Using the SOH identity
sinx = opposite/hypotenuse
sin x = 16/21
sin x = 0.7619
x = arcsin 0.7619
x = 49.6° (to the nearest tenth of a degree)
3^2 is equal to 9 and that is the right answer
