Master The Angle

Lines that intersect to form a right angle.

The total sum of complementary angles.

What kind of angle has a measure of $$359\degree$$ ?

$$\frac{1}{2}\left(m\angle NMS+m\angle SMY\right)$$

$$m\angle NMS=160\degree\ \ \ \ \ m\angle SMY=20\degree$$

$$\left(-2\left(m\angle NMI-m\angle SMY\right)\right)^2$$

$$m\angle NMI=5\degree\ \ \ \ \ \ m\angle SMY=20\degree$$

(a)   is the measure of an angle.
