Calculus
In triangle PQR, angle P is 20 degres, angle R is 150 degrees, and QR is 6, the length of PQ is...?

Calculus
Sorry, I just really suck at trigonmetry, and Im in grade 11.

Calculus
P (-V3/2, -1/2 and Q(1/2, V3/2 are two points on the unit circle. If an object rotates counterclockwise from point P to point Q, what angle has it rotated? 180 + 60 = 330 P 60 Q I got like 300, but its supposed to be 210 degrees:\

Calculus
Find the exact values of the following. cos 270 degrees = 90 degrees, value = 0. Sin 180 degrees = 180-90 = 90 = 1, but its supposed to be zero, dont know how to get that:\ Confused with tan 240 degrees as well.

Calculus
Determine the measure of A if 0 degrees is less or equal to angle A and if angle A is less or equal to 360 degrees. Tan A = 0 Answer is somehow supposed to be 0 degrees, 180 degrees, and 360 degrees, but dont know how to get the answer, just really confused. Sin A = -1

Calculus
Fine the measure of feta, to nearest degree, where 0 degrees is less or equal to feta, and feta is less or equal to 360 degrees. tan feta + 5 = 0, I tried working this out and I got -78.6:\

Calculus
The point A(-3, -5) is one the terminal arm of an angle feta. Determine the exact expressions for the primary trigonmetric ratios for the angle. Would that be 225 degrees. -2V2?

Calculus
Thank you, so would I use those expressions to find the area? Would I times 8sin60 by 8 cos60?

Calculus
A rectangle has a diagonal of 8cm. The diagonal creates a 60 degrees angle at the base of the rectangle. Write an exact expression for the base and the height of the rectangle. ^^ Dont get how to do that, Ive only drawn a triangular diagram, and im confused about the expressio...

Calculus
Determine two angels between 0 degrees and 360 degrees that have a sine ratio of -1/2. Would that be 30 and 330?
