Just pick a number
i’ll pick 2
and solve the equations
1. 6(2+12)
12+72
84
2. 6(2)+12
12+12
24
3.3(2(2)+4)
3(4+4)
3(8)
24
your answer is D
expressions 2 and 3 are equivalent
Supplementary angles equal to 180
So, adjacent angle + exterior angle = 180
adjacent angle = 180 - 155 = 25
Now, non-adjacent + adjacent = 90
non-adjacent = 90 - 25 = 65
So 65 degrees is your answer.
A' = (- 3, 0 )
(x, y ) → (x - 5, y + 2 ) means subtract 5 from the original x-coordinate and add 2 to the original y- coordinate
A(2, - 2 ) → A'(2 - 5, - 2 + 2 ) → A'(- 3, 0 )
A circular plot is watered by a sprinkler that rotates through it. The sprinkler only rotates through a semi-circle, or half of the whole circle.
Area of a circle: A = pi x r^2
r = 160 / 2 = 80
A = pi x 80^2
A = 6400pi / 2 = 3200pi
3200pi = 10053.0965
The area water is approximately 10,053 ft^2.
Hope this helps!! :)
