A). They are supplementary angles meaning they add up to 180
So
B) (12x+8)+(3x+7)=180
12x+8+3x+7=180
15x+15=180
-15 -15
15x=165
15/15x=165/15
x=11
Angle 1 is
12x+8
12(11)+8
132+8
140
Therefore measure of angle 1 is 140°
Angle 2
3x+7
3(11)+7
33+7
40
Measure of angle 2 is 40°

Step-by-step explanation:
Answer: 0.49668352
Step-by-step explanation:
Given : The unemployment rate : p = 20%= 0.20
Sample size : n =8
Let x be the binomial variable that represents the number of unemployed residents.
Binomial probability distribution formula : 
The probability that at least two of the residents were unemployed :





Hence, Required probability =0.49668352
