Answer:
1.5
Step-by-step explanation:
225° bisects Q III
315° bisects Q IV
-270° = 90°
405° = 45° bisects Q I
cos(225) sin(315) + sin( –270) tan(405) = ?
(-½√2)(-½√2) + 1(1) = ?
0.5 + 1 = 1.5

Answer:

Step-by-step explanation:
By definition, tangent lines touch a circle at one point. This one point intersects the circle at a 90 degree angle.
In any circle, the measure of an inscribed angle is exactly half of the arc it forms. Since
forms an arc labelled 244 degrees, the measure of angle 2 must be
.
Angle 1 and 2 form one side of a line. Since there are 180 degrees on each side of the line, we have:
