What is the measure of angle AXB?

Answer:
Step-by-step explanation:
Two angles are supplementary when their sum is 180
∠AXB + ∠BXC = 180° {Supplementary angles}
8x + 10 + 2x - 20 = 180
Add the like terms
10x - 10 = 180
10x = 180 + 10
10x = 190
x = 190/10
x = 19°
∠AXB = 8x + 10
= 8 * 19 +10
= 152 + 10
∠AXB = 162
Answer:
180 degrees
Step-by-step explanation: the measure of angle AXB is ( a + a ) and the sum of the measured angles AXB and BXC = 180 , so a + ( a + a) = 180.
both these angles add up to be 180 degrees because they are both supplementary angles they both share the sides of x and b.
if it confuses you, just use a bit of repeated addition and multiplication
for example : 30 + 30 + 30 + 30 + 30 = 5 x 30 which equals to 150
because you add 30 , 5 times .
