Find one positive and one negative angle coterminal with an angle of 11pi/8

It's 27pi/8 and -5pi/8.

Step-by-step explanation:

You add and subtract 2pi to your answer to get coterminal angle.

2pi=360 degrees which is one circle.

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
