The answer to this question is a equilater triangule
Answer:
56 square inches
Step-by-step explanation:
1/2x4x3x2 is 12
4x11 is 44
44+12 is 56
Answer:
18 π cm^2.
Step-by-step explanation:
The area of the whole circle = π r^2 = 81π cm^2.
Since there are 360 degrees in a circle the area of the shaded region =
80/360 * area of the circle.
This = 80/360 * 81 π
= 2/9 * 81 π
= 18 π
4y + x = 4 . . . . . . . (1)
2y - x = 8 . . . . . . . (2)
(1) + (2) => 6y = 12
y = 12/6 = 2
From (2), 2(2) - x = 8
4 - x = 8
x = 4 - 8 = -4
Therefore solution is (-4, 2) and lies on both lines.
