4ˣ⁻¹ = 49 / 4
<h3>How to simplify an expression?</h3>
The expressions can be simplified as follows;
Hence,
Therefore,
Finally,
2ˣ = 7
4ˣ⁻¹ = 2²⁽ˣ⁻¹⁾ = 2²ˣ ⁻ ² = 2²ˣ / 2² = (2ˣ)² / 2²
Therefore,
(2ˣ)² / 2² = 7² / 2² = 49 / 4
Hence,
4ˣ⁻¹ = 49 / 4
Finally, the is equal to 
and for the second part 4ˣ⁻¹ = 49 / 4

And that is how you get your answer
It’s called the vertex and the two rays are called the sides of the angle.
Answer:
111 boxes
Step-by-step explanation:
He bought 223 feet of wood
Each box will take 2 feet
To determine the total number of box he'll make from 223,
1 box = 2 feet of wood
X box = 223 feet of wood
X = (223 × 1) / 2
X = 111.5 box approximately 112 boxes
But technically, since its 111.5, he'll be able to make 111 boxes completely with 0.5 feet of wood left
First thing solve for missing side using Pythagorean theorem 20^2=16^2+a^2 then solve for a and we get a=12. Then we can use Toa which means tan=o/a so if we plug in those values we get tan(theta)=16/12
