2. When the central angle is 45 degrees, how can you use what you know about the Pythagorean theorem and triangles to find the sine and cosine if the radius of the circle is 1? *

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

answer: the answer is 110

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12
