Answer:
13
Step-by-step explanation:
It is a parallelogram so the opposite angles are the same.
All angles sum to 360 degrees.
This means that the adjacent angles sum to 180 degrees.
4a + 11 + 9a = 180 = 13a + 11
13a = 169
a=13
the answer is 11/7 feet because the perimeter of a circle is πr² and a semi circle is half of a circle then the formula would be 1/2 πr² 1/2×22/7×1 (it is 1 because we have divided the diameter to get radius so we derived at 11/7.
Try this solution, check, please, issue no.4.
To find what the y value is, we just have to input the x value and solve.
y =
x + 2
y =
* 2 + 2
y =
+ 2
y = 3.2
That means that the missing half of the coordinate is
3.2.
The answer is 31/6 which is also 5 1/6
