Answer:
45 is 62.5% of 72
Step-by-step explanation:
72x = 45
x = 45/72 = 0.625 = 62.5%
6^2 + 17 + 12
First, let's start with
![6^{2}](https://tex.z-dn.net/?f=%206%5E%7B2%7D%20)
. Basically, the '2' above the 6 indicates that the number appears twice in multiplying.
![6^{2}](https://tex.z-dn.net/?f=%206%5E%7B2%7D%20)
can be described as 6 × 6 as well. 36 should be your answer for 6 squared.
![6^{2} = 6 \times 6 = 36](https://tex.z-dn.net/?f=%206%5E%7B2%7D%20%3D%206%20%5Ctimes%206%20%3D%2036)
Second, our problem should look like: 36 + 17 + 12. One can simply do this on a calculator or count on their fingers. Once you add all of the numbers up, you should get 65.

Step-by-step explanation:
This question is asking us to find where sin(2x + 30) has a sin of 1. If you look at the unit circle, 90 degrees has a sin of 1. Mathematically, it will be solved like this (begin by taking the inverse sin of both sides):
![sin^{-1}[sin(2x+30)]=sin^{-1}(1)](https://tex.z-dn.net/?f=sin%5E%7B-1%7D%5Bsin%282x%2B30%29%5D%3Dsin%5E%7B-1%7D%281%29)
On the left, the inverse sin "undoes" or cancels the sin, leaving us with
2x + 30 = sin⁻¹(1)
The right side is asking us what angle has a sin of 1, which is 90. Sub that into the right side:
2x + 30 = 90 and
2x = 60 so
x = 30
You're welcome!
