Answer:

D

Step-by-step explanation:

Since you are trying to make x on its own, you are trying to get rid of the co-efficient. The co-efficient is three, so you divide 3 by 3, which would equal one, leaving x on its own. Whatever you do to one side you do to the other, so you would divide 27 by 3 as well.

x = 9

Find the missing angle:
sergey [27]

Answer:

40

Step-by-step explanation:

Going from left to right

We need to find the angle from the first triangle

The sum of the angles of a triangle is 180

80+25+x = 180

Combine like terms

105+ x = 180

Subtract 105 from each side

105-105+x = 180-105

x = 75

Then we have 3 angles that make a straight line and a straight line is 180

x + 50 + y = 180

75+ 50 + y = 180

Combine like terms

125 + y = 180

Subtract 125 from each side

125-125+y = 180-125

y = 55

We now have the triangle on the right

The angles add to 180

55+85+ ? = 180

Combine like terms

140+ ? = 180

Subtract 140 from each side

140+?  - 140 = 180-140

? = 40

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).
