You are expected to know (-x)*(-x) = x^2 = (x)*(x) for any value of x.
With this in mind, you expect to be looking for squares in answer to your question. You will find them.
1) y² = 49 . . . . . . . 4th selection
2) y² = 16 . . . . . . . 3rd selection
Answer:
tan teeta = <u>oppos</u><u>ite</u>
adjacent
45°= <u>7</u>
x

which will now give us
<u>45°x</u>=<u>7</u>
45°. 45°
x= 0.16
