Answer:
<em>y = 12.3 cm</em>
Step-by-step explanation:
This is a right triangle, so we can use sin,cos, or tan to solve this.
First, with respect to the angle 35 degrees, we can say "y" is the "adjacent side".
Also, the hypotenuse is given as 15.
<em>Which trig ratio relates adjacent and hypotenuse? That is COS. So we can write and solve the equation below:</em>

<em>Rounded to 1 decimal place (nearest tenth) , </em>
<em>y = 12.3 cm</em>
1. C=2πr
We need to move r by itself on a side of the equation.
Divide both sides of the equation by 2π. This will cancel out the side with the r.
r=C/2π
2. A=1/2*b*h
Divide both sides by 1/2*h, isolating b
b=A/h
3.y=mx+b
Now we have to do reverse PEMDAS, we have to add/subtract before we can multiply or divide to simplify.
Subtract both sides by b
y-b=mx
Now divide both sides by m
x=
Remember we have to divide both terms y and -b by 2, so it goes on the bottom for both.
