Find the measure of each side indicated. Round to the nearest tenth.
23)
We have a 30-60-90 right triangle
The hypotenuse "x" is twice the measure of the side opposite the 30° angle
So....
x = 10
24)
We know an angle, the hypotenuse and we are trying to find the adjacent side
The cosine seems the way to go....
cos 70° = x / 10 multiply both sides by 10
10 * cos 70° = x ≈ 3.42
