If m/2 = 40°, what is the measure of 1 + 6? Notice that you are to find angle 1 plus angle 6.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
