Answer:
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!
Betina is 155 centimeters tall or 1 meter and 55 centimeters
1 meter = 100 centimeters
100 + 87 = 187 , Brian’s height in centimeters
Since Bonnie is 58 centimeters shorter we will subtract 187-58 which gives us 129 centimeters.
Betina is 26 centimeters taller than Bonnie so we add 26+129 =155
Therefore Betina is 155 centimeters tall or 1 meter and 55 centimeters.
Hope this helped! :)
