In ΔGHI, the measure of ∠I=90°, IG = 48 feet, and HI = 22 feet. Find the measure of ∠G to the nearest tenth of a degree.

Answer:
50.7°
Step-by-step explanation:
We need to use the only two known sides of the triangle to find the measure of angle G.
Looking from angle G, what is it's relationship to side IG?
It is an adjacent side.
Looking from angle G, what is it's relationship to side HI
It is an opposite side.
We know that the tangent ratio uses the opposite and adjacent sides.
tan = opp/adj
Let's substitute the values we know into this equation:
tan = opp/adj
tan ∠G = HI/IG
tan ∠G = 22/18
Now, use your calculator to find the value of angle G.
*Remember to be in degrees and use inverse tan*
tan ∠G = 22/18
tan ∠G ≈ 50.7
Therefore, the measure of angle G is about 50.7 degrees.

The function has an inverse that is also a function is g(x) = 2x – 3.
The correct option is A.
<h3>Inverse function;</h3>The inverse of a function is the equation where x and y have switched places.
We have to determine
Which function has an inverse that is also a function?
If when you solve for y again, the function passes the vertical line test, the inverse if a function.
1. Here g(x) = 2x - 3 has inverse x = 2y - 3 which simplifies to;
This is a line and is a function;
2. k(x) = -9x^2 has the inverse x = -9y^2 which simplifies to;
This is a function but only for certain values of x.
3. f(x) = |x+2| is an absolute value function.
All absolute value functions do not have inverses which are functions.
4. w(x) = -20 does not have an inverse which is a function.
Hence, the function has an inverse that is also a function is g(x) = 2x – 3.
