If the angle at the top of the tower is known, a surveyor would use the a0 function9 to find the length x. The cosine of a 50° angle is a1 this represents the value created when length a2 is divided by a3 feet. If the angle near the top of the tower was changed to 60°, the cosine would be 0.5; now the length of x would be a4 feet. If the angle near the top of the tower was changed to 60°, the angle from the light and the ground would be a5 degrees.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

imma say 16%. sorry if its wrong. i'm doing the same stuff right now
