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).

The perimeter of the triangle is 40 units.Which of the following equations could be used to find the value of x?
Artyom0805 [142]

Answer:

13x + 112 = 320.

Step-by-step explanation:

The perimeter is the sum of the 3 sides:

1/2 x + 3/8 x + 11 + 3/4 x + 3 = 40

1/2 x + 3/8 x  + 3/4 x + 3 + 11 = 40

1/2 x + 3/8 x  + 3/4 x + 14 = 40

Multiply through by 8 to remove the fractions:

4x + 3x + 6x  + 14 = 40

13x + 112 = 320.
