ANSWER

44.43°

Step-by-step explanation

We have a right triangle and we know the lengths of the hypotenuse and the opposite leg to the unknown angle, so we can use the sine of the angle to find it,


\sin \theta=(7)/(10)

Solving for θ,


\theta=\sin ^(-1)\mleft((7)/(10)\mright)

Now, using a calculator, we find that the angle is 44.43°, rounded to the nearest hundredth of an angle.
