Which represents the area of the shaded region?
area of the circle – area of the square – area of the triangle
area of the triangle – area of the square + area of the circle
area of the triangle + area of the square + area of the circle
area of the circle – area of the triangle + area of the square
The area of the shadedregion is (area of the circle) - (area of the square) - (area of the triangle)
Option A is the correct answer
A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
The shadedregion consists of the area inside the circle but outside the square, as well as the area inside the equilateral triangle but outside the square.
Now,
The area of the circle is πr²
Since the square is inscribed in the circle, the diameter of the circle is equal to the diagonal of the square.
Let's say the side length of the square is s.
By the Pythagorean theorem,
s² + s² = (diameter)²
2s² = (2r)²
s² = r²
The area of the square is s² = r².
The area of an equilateraltriangle with side length s is √(3)/4 x s².
Since the side length of the square is equal to the height of the equilateral triangle, the side length of the equilateral triangle is also equal to s.
The area of the shadedregion.
= (area of the circle) - (area of the square) - (area of the triangle)
Thus,
The area of the shadedregion is (area of the circle) - (area of the square) - (area of the triangle)

The value of g(f(-3)) would be -9 which is the correct answer would be an option (B).
A function is defined as a mathematical phrase that specifies a connection between two variables in algebra.
We have been given the functions below as
f(x) = 3x + 7 and g(x) = 2x - 5
We have to determine the value of g(f(-3))
Substitute the value of f(x) = 3x + 7 in the g(x) = 2x - 5 to get g(f(x))
⇒ g(f(x)) = 2(3x + 7) - 5
Apply the distributive property of multiplication,
⇒ g(f(x)) = 6x + 14 - 5
⇒ g(f(x)) = 6x + 9
Substitute the value of x = -3 in the g(x) = 2x - 5 to get g(f(-3))
⇒ g(f(-3)) = 6(-3) + 9
⇒ g(f(-3)) = -18 + 9
⇒ g(f(-3)) = -9
Therefore, the value of g(f(-3)) would be -9.

Answer:13111111/200000000
If UVW =~(congruent symbol) EFC, what is the measure of
The measure of angle FEC from the given triangle FCE is 51°. Therefore, option D is the correct answer.
Given that, ΔUVW≅ΔEFC.
Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.
From the given triangle UVW, the measure of ∠U=51° and ∠W=82°.
We know that, the corresponding parts of congruent triangle are equal.
Here, ∠FCE=∠W=82°
∠FEC=∠U=51°
The measure of angle FEC from the given triangle FCE is 51°. Therefore, option D is the correct answer.

Answer:
D. 51
Step-by-step explanation:
If UVW is congruent to EFC then FEC must be congruent to VUW
VUW= 51 so FEC= 51
