What are the coordinates for the angle π/4 on tge unit circle

Both x and y are which is the same as

In other words, the point is on the unit circle for the angle pi/4 radians. This point is equivalent to

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

Explanation:

The angle pi/4 radians is equivalent to 45 degrees. Draw out a 45-45-90 triangle with hypotenuse 1, and you'll find the congruent legs are each units long (apply the pythagorean theorem). If you apply the sine and cosine ratios, you'll get the answer shown above.

Recall that

and also

The pythagorean theorem is a^2+b^2 = c^2.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

answer: answer: d) v= 1/6 bh
