Step-by-step explanation:
We know that area of Trapezium =
1/2 * (16+48) * 20
= 640 m²
Now, for semicircle,
1/2 * pi * r²
= 1/2 * 3.14 * 18.86 * 18.86
= 558.44 m²
Adding both,
1198.44 m² ~ 2000 m²
Hope it helps :)
Answer:
Step-by-step explanation:
Given that,
y=x+2 equation 1
2x-y=-4 equation 2
This is a simultaneous equation.
Substitute equation 1 into equation 2
2x-y=-4. Since y=x+2
2x-(x+2) = -4
2x-x-2 = -4
x-2 = -4
x = -4+2
x = -2
Also from equation 1
y=x+2
Since x=-2
y=-2+2
y=0
Then, solution (x, y) = (-2,0)
Answer:
-2/5
Step-by-step explanation:
The answer is 128 degrees because complimentary angles have to equal 180 and 128 is the only answer that adds up with 52 to get 180
