Answer:
(-1,2)
Step-by-step explanation:
A. Parallel Postulate
That type of statement is accepted without any proof
Considering the figures, the area that will be painted is of 38.9 square feet.
<h3>What is the area of a rectangle?</h3>
The area of a rectangle of length l and width w is given by:
<h3>What is the area of a triangle?</h3>
The area of a triangle of base b and height h is given by:
<h3>What is the area of a semi-circle?</h3>
The area of a semi-circle of radius r is given by:
In this problem:
- The rectangle with l = 6 ft and w = 8 ft will be painted, along with the triangle of dimensions b = 8 ft and h = 4 ft.
- The semi-circle with r = 4 ft will not be painted.
Hence, the area that will be painted, in square feet, is given by:

Y would be 3 then.
Beacuse the equation is y=Mx+c
So if you substitute the values it will be
y=2(0)+3
Y=0+3
Y=3
Suppose we have a triangle ΔABC,
Length of AB = 14
Length of AC = 14
Angle ∠BAC = 122 degree
This triangle is isosceles triangle so, angle B = angle C = (180 - 122)/2 = 29
We know the two side and one angle of triangle ABC, here we use Sine Rule.
(In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of a triangle (any shape) to the sines of its angles.)
According to the law,
Solve for a
a = 24.49 option C
