In the adjoining figure, ABCD is an isosceles trapezium in which angle BCD= 2x and angle ABC=3x. Find all the angles of the trapezium.
The trapezium is an isosceles trapezium. Then the measure of all angles will be 54°, 36°, 36°, and 54°.
What is a trapezium?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a trapezium, one pair of opposite sides are parallel.
In the adjoining figure, ABCD is an isosceles trapezium in which angle ∠BCD = 2x and angle ∠ABC = 3x.
Then all the angles of the trapezium will be
Agngle ∠BCD = ∠ADC and angle ∠ABC = ∠BAD because the trapezium is an isosceles trapezium. Then we have
Then the value of x will be
∠ABC + ∠BCD + ∠CDA + ∠DAB = 180°
3x + 2x + 2x + 3x = 180°
10x = 180°
x = 18°
Then the measure of all angles will be
∠ABC = ∠BAD = 3x = 3 × 18 = 54°
∠BCD = ∠ADC = 2x = 2 × 18 = 36°

Answer:
x = 88 degrees
Step-by-step explanation:
Its really easy. All you have to do is subtract all the known angles from 360 since a quadrilateral has 360 degrees
360 - 106 - 114 - 52 = 88
Hope this helped!
Answer:
x = 88°
Step-by-step explanation:
Quadrilaterals: Sum of all angles of quadrilaterals = 360°x + 52 + 114 + 106 = 360°
x + 272 = 360
x = 360 - 272

Determine the equation of a cubic of the form
y=ax^3+bx^2+c if the cubic has a y-intercept of (0,3) and passes through the points (1,6) and (-1,4).
========================================================
Explanation:
If you plug in x = 0 and y = 3, then the original equation boils down to c = 3. The x = 0 cancels out pretty much everything except that c term.
We have y=ax^3+bx^2+c update to y=ax^3+bx^2+3
Now plug in x = 1 and y = 6 from the point (1,6)
y=ax^3+bx^2+3
6=a(1)^3+b(1)^2+3
6 = a+b + 3
a+b = 6-3
a+b = 3
Now plug in the coordinates of (-1,4) which are x = -1 and y = 4
y=ax^3+bx^2+3
4=a(-1)^3+b(-1)^2+3
4 = -a + b + 3
-a+b = 4-3
-a+b = 1
-----------------------------
Here are the two equations we're interested in
a+b = 3
-a+b = 1
We'll add these equations straight down. The 'a' terms cancel. The b terms add to 2b. The right hand sides add to 3+1 = 4
We're left with 2b = 4 and it solves to b = 2
Use any of the equations involving 'a' and b to determine that a = 1
-----------------------------
To summarize we have
a = 1
b = 2
c = 3
This means y=ax^3+bx^2+c updates fully to y=1x^3+2x^2+3 which simplifies to y = x^3+2x^2+3 and it's the final answer.

Find the Area of the figure below, composed of parallelogram and two semicircles.
Round to the nearest tenths place.
Answer:
622.13 square units
Step-by-step explanation:
Area of the composite figure = area of parallelogram + area of circle
Note: 2 semicircles = 1 full circle
Area of the figure = a*h + πr²
Where,
a = 22
h = 11
r = ½ of 20 = 10
Plug in the value into the equation
Area = 22*11 + π*11²
Area = 242 + π*121
Area = 622.13271108 ≈ 622.13 square units (nearest tenth)

What is the solution to the system of equations?
5x – 4y = -2
2x + 4y = 16
Answer:
x = 2, y = 3
Step-by-step explanation:
5x – 4y = -2
2x + 4y = 16
Solve by elimination. (-4y and +4y gives 0)
7x = 14
x = 2
Substitute 2 in one of the equations in order to find y.
5(2) - 4y = -2
10 - 4y = -2
-4y = -12
y = 3
x = 2, y = 3

Answer: 226.56 m²
Step-by-step explanation:
We need to find the area of three rectangles and two triangles.
The triangles: 34.56 m²
A = [tex]\frac{B*H}{2}[/tex]
-> Since they are both congruent, we will skip dividing by two
A = B * H
A = 7.2 * 4.8
A = 34.56 m²
The rectangles: 192 m²
A = L * W
-> We have two that are congruent, and one that is not
A = 10 * 6 * (2, since there are two)
A = 120 m²
-
A = L * W
A = 7.2 * 10
A = 72 m²
-
72 m² + 120 m² = 192 m²
Total surface area:
34.56 m² + 192 m² = 226.56 m²
