Answer:
a. x = 14 (see explanation)
b. the arrows along the lines
Step-by-step explanation:
The relationship of these two expressions is Same Side, which means their sum is 180.
<u><em>plugging</em><em> </em><em>in</em></u>
108 + 4x + 16 = 180 | Given
124 + 4x = 180 | Add the numbers
4x = 56 | Subtract 124 from both sides
x = 14 | Divide both sides by 4
Answer:
82 degrees
Step-by-step explanation:
Measure of arc ABC = 86*2 = 172 degrees.
Measure of arc DC = 360 - (145+172) = 360-317 = 43 degrees.
Measure of arc BCD = 121+43 = 164 degrees.
Measure of angle A = 164/2 = 82 degrees
