What is the value of y?

There are two things to know. With a 45-45-90 triangle, the hypotenuse
(longest side) is the shorter side multiplied by √2. So you would multiply √2 * √2 = 2. The hypotenuse of the 45-45-90 triangle. Next we use the second thing to know. In a 30-60-90 triangle. the shorter leg is x, the longer leg is x * <span>√3, and the hypotenuse is 2x. Since y is the longer leg, we use 2x. y = 2(2) = 4. y = 4</span>

Hello!
As you can see, we have a radius of 6. If we divide, this means that this is 2.5 radians. To convert radians to degrees we use the formula below.
First of all we divide 180 by pi.
180/
≈57.3
Now we multiply by 2.5
57.3(2.5)=143.25°
Note that the angle we see is obtuse, or greater than 90°.
Therefore, ∠<span>θ</span>≈143.25°
Now we need to convert this back into radians. This can be represented by the equation below.
First we divide pi by 180 then multiply by our angle.
/180(143.25)≈2.5
Therefore, our angle theta is about 2.5 radians.
I hope this helps!
