The distance between Durham to Birmingham is 240 miles
Answer:
The equation is;
(2x-2) + (4x + 2) = 180
x = 30
m∠A = 58
Step-by-step explanation:
Mathematically, when two angles are supplementary, the values of both angles add up to be 180
From
what we have here;
(2x -2) + (4x + 2) = 180
2x -2 + 4x + 2 = 180
6x = 180
x = 180/6
x = 30
Recall;
The measure of angle A is as follows;
2x -2 = 2(30) - 2 = 60-2 = 58
Answer:
96
Step-by-step explanation:
Negative seventeen multiplied by negative six times results in 96, as multiplying a negative by a negative results in a positive and that 17*9 is 96.
Explanation:
x+91 and x+111 are supplementary angles (they add up to 180), so you would set an equation by adding both of them to equal 180:
x + 91 + x + 111 = 180
add like terms
2x + 202 = 180
subtract 202 from both sides
2x = -22
divide both sides by 2 to get the answer:
x = -11
