1 answer:
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).

Answer:1,76,000 Profit
Step-by-step explanation:
Given
Jesse initially bought the car for 2,200,000 and sold it for 20 %
S.P.=C.P.(1+Profit%)
so, the Selling price of the car is S.P.=
profit=2,640,000-2,200,000=4,40,000
After this, he bought another car and sells it for a 10 % loss
So, the selling price of the car is
loss=2,640,000-2,376,000=2,64,000
Net Profit or loss=4,40,000-2,64,000=1,76,000 Profit
