The question is in the image. Answer question 18 only.

Answer:
135 degrees.
Explanation:
We need to convert 3π/4 radians to degrees. Since we know that π radians are equivalent to 180 degrees, we can convert 3π/4 as follows
[tex]\frac{3\pi}{4}\text{ rad}\times\frac{180\text{ degrees}}{\pi\text{ rad}}=\frac{3\pi\times180}{4\times\pi}=135\text{ degrees}[/tex]Therefore, the measure in degrees is 135 degrees.
