Answer:
-663
Step-by-step explanation:
The nth term of an arithmetic sequence is:
aₙ = a₁ + d (n − 1)
The first term is -14, and the common difference is -11. So the nth term is:
aₙ = -14 + (-11) (n − 1)
So the 60th term is:
a₆₀ = -14 + (-11) (60 − 1)
a₆₀ = -663
In Quadrant IV, x is positive and y is negative
Answer:
M=3
Step-by-step explanation:
- 4-m/2=10
- subtract 4 from each side
- get m/2=6
- then divide 2 from 6 and get m=3
Hope this helps:)
What's the question exactly?
To solve this
problem, we must remember that the sum of interior angle of a polygon is:
Sum of
interior angles = (n – 2) * 180˚
So, we can say
that:
Sum of
interior angles = angle A + angle B + angle C + angle D = (4 – 2) * 180˚
Where,
angle C + angle
D = 110 + 70 = 180˚
Therefore
substituting this value:
angle A + angle
B + 180˚ = 2 * 108˚
angle A + angle
B = 360˚ - 180˚
angle A + angle
B = 180˚ (answer)
Hence we can
also conclude that,
<span>angle A + angle
B = angle C + angle D</span>
