Angle e = x angle d = 5x supplementary means they add up to 180
x + 5x =180
6x = 180
6x/6 = 180/6
x = 30
so angle e = 30 and angle d = 5(30) = 150
Answer: B) 18° C
Step-by-step explanation:
21+(-3) = 21 - 3
= 18
Answer:
This is an arithmetic sequence with a common difference <em>d</em> of -5
Step-by-step explanation:
When you find out <em>d</em>, you realize the difference between the numbers to be -5. Since it is <em>d</em> and not common ratio <em>r</em>, it is an arithmetic sequence.
