What are the rounded answers to each question?

For the given triangle, m∠G° = 51°, HI = 23.3 units, and GH = 18.9 units.

Step-by-step explanation:

Step 1:

In the triangle, the given angle is 39°, the hypotenuse side's length is 30 units. Assume the opposite side's length is x units.

To determine the opposite side's length, we determine the sin of the angle. To calculate the sin of an angle, we divide the opposite side's length by the hypotenuse's length.

GH measures 18.879 units. Rounding this off, we get 18.9 units.

Step 2:

Assume the side HI measures y units. According to Pythagoras' theorem,

So HI measures 23.314 units. Rounding this off, we get 23.3 units.

Step 3:

GHI is a triangle and all triangles have a total angle of 180°.

So ∠G° measures 51°.
