Let the measure of the smaller angle be x, then the larger angle is 5 + 6x and
x + 5 + 6x = 180
7x + 5 = 180
7x = 180 - 5 = 175
x = 175/7 = 25
The larger angle is 5 + 6(25) = 5 + 150 = 155 degrees.
C I believe it not so sure
You mean their sum is 12?
A) x + y = 12
B) x -y = 4 then we add both equations:
2x = 16
x = 8
y = 4
The term for this sequence is 2.
It's an easy pattern!..
The second term is two times two.
The third term is two times three and so on..
