Brums [2.3K]3 years ago

Answer: sqrt(2)/2  which is choice D

======================================================

Explanation

(3pi/4) radians converts to 135 degrees after multiplying by the conversion factor (180/pi).

The angle 135 degrees is in quadrant 2. We subtract the angle 135 from 180 to find the reference angle

180-135 = 45

Then you can use a 45-45-90 triangle to determine that the ratio of opposite over hypotenuse is sqrt(2)/2

sine is positive in quadrant 2

------------

Alternatively, you can use a unit circle. Refer to the diagram below. In red, I've circled the angle 3pi/4 radians. The terminal point for this angle has a y coordinate of sqrt(2)/2

Recall that y = sin(theta).

What is the measure of each interior angle of a regular decagon (10 sides)?
bixtya [17]
6)a

if we put n as the number of sides in a regular polygon, the formula to find the measure of each angle is
\frac{(n - 2) \times 180}{n}
so the answer will be
\frac{(10 - 2) \times 180 }{10}   = \frac{1440}{10}  = 144
they each measures 144 degrees




good luck
