Answer:
Explanation:
This is aright angle triangle, we can apply any of the trigonometry ratio formulae
SOH, CAH TOA
We can apply any of them since we know the opposite, adjacent and the hypotenuse
Therefore, let use sin
Sinx=opposite / hypotenuse
Opposite is the side facing the unknown angle while hypotenuse is the longest side or the side facing the right angle triangle
Then, opposite is 45 and hypotenuse is 53
Sinx= opp/hyp
Sinx=45/53
Sinx=0.8491
x=arcsin(0.8491)
x=58.11°
x is approximately 58°
The last option is the correct option
