Answer:
The best way to measure an angle is to use a protractor.
Step-by-step explanation:
To do this, you'll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle's measurement to the nearest degree
- Picture A
Determine the measure of angle x :
Add together the known angles.
68° + 47° = 115°
Subtract the sum from 180°.
180° - 115° = 65°
The measure of angle x is 65°.
Picture B
Determine the measure of angle m :
Subtract the know angle from 180°.
180° - 26° = 154°
Divide the difference by 2 to get the measure of each angle.
154° ÷ 2 = 77°
Each angle m measures 77°.
