Find the measure of O?
Line UV is a supplementary line. Line UV is 180 degrees. Angle TU is 30 degrees. Angle WV is 65 degrees. Angle TW (O) is unknown. Add the given angles. 30+65=95 degrees. Subtract the sum of the two angles from 180 degrees. 180-95=85. O is 85 degrees
3. 12 a
4. 7b-10
all you have to do is add up all of the sides.
The answer is 142°
Explanation:
angle 1 and angle 2 form are supplementary.
m∠1 + m∠2 = 180°
38° + m∠2 = 180°
m∠2 = 180° - 38°
m∠2 = 142°
