A circle has a sector with a area 3/2 pi and central angle of 60 degrees. What is the area of the circle?

Can you draw an isosceles triangle with only one 80 degree angle?

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above

What is the area of triangle abc if a = 8, b = 11, and c = 15?
