Answer:
h = 17 units
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the height and b₁ , b₂ the parallel bases
Here A = 408, b₁ = 20, b₂ = 28 , then
[tex]\frac{1}{2}[/tex] h (20 + 28) = 408 ( multiply both sides by 2 to clear the fraction )
48h = 816 ( divide both sides by 48 )
h = 17

What is a circle?A circle is a collection of all points in a plane which are at a constant distance from a fixed point. A circle is a round-shaped figure that has no corners or edges.
For the given situation,
In the figure, GB and GD are the secants of the circle.
In circle, intercept two arcs such that the measure of the angle that the segments form is equal to one-half the difference of the measures of the intercepted arcs. Thus arc length can be found as
[tex]\frac{1}{2}(mBD-mFE)=m \angle BGD[/tex] -------- (1)
Here, BD = [tex]35+100[/tex]
⇒ [tex]135[/tex]
FE = [tex]x[/tex]
m∠BGD = 55°
Now, equation 1 becomes
⇒ [tex]\frac{1}{2}(135-x)=55[/tex]
⇒ [tex](135-x)=55(2)[/tex]
⇒ [tex]135-x=110[/tex]
⇒ [tex]x=135-110[/tex]
⇒ [tex]x=25[/tex]
Hence we can conclude that the value of measure of arc FE is 25°.

Competency: Write the linear equations Ax + By = C. Give the value of A,B, and C,.
Answer:
see explanation
Step-by-step explanation:
(1)
y = - x + 4 ( add x to both sides )
x + y = 4
with A = 1, B = 1, C = 4
(2)
y = 5x + 7 ( subtract y from both sides )
0 = 5x - y + 7 ( subtract 7 from both sides )
- 7 = 5x - y , that is
5x - y = - 7
with A = 5, B = - 1, C = - 7
----------------------------------------------------------
(1)
2x + y = 9 ( subtract 2x from both sides )
y = - 2x + 9
with m = - 2, c = 9
(2)
5x + 2y = 7 ( subtract 5x from both sides )
2y = - 5x + 7 ( divide terms by 2 )
y = - [tex]\frac{5}{2}[/tex] x + [tex]\frac{7}{2}[/tex]
with m = - [tex]\frac{5}{2}[/tex] , c = [tex]\frac{7}{2}[/tex]

Find the surface area of a sphere with radius 9 using the formula SA=4nr2
Leave answer in terms of n
A. 20 n units2
B. 25 n units2
C. 100 n units2
Answer:
972 u³
Step-by-step explanation:
The radius is 9 . We can use formula ,
⇒ V = 4/3 π r³
⇒ V = 4/3 × π × 9³
⇒ V = 4 × π × 81 × 3
⇒ V = 972 unit³

The area of a sector of a given circle is 37.7 m².
Given that, the radius of a circle=4 m and the central angle of a circle=270°.
What is the formula to find the area of a sector?The area of a sector is the space inside the section of the circle created by two radii and an arc. It is a fraction of the area of the entire circle.
The formula to find the area of a sector is θ/360°(πr²).
Where r is the radius of the circle and θ is the angle of the sector.
Now, area=270°/360°(3.14×4×4)=37.68≈37.7 m².
Therefore, the area of a sector of a given circle is 37.7 m².

Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (- 5, 3 ) and r = 4 , then
(x - (- 5))² + (y - 3)² = 4² , that is
(x + 5)² + (y - 3)² = 16 → D

Answer:
50 Degrees
Step-by-step explanation:
Since they already have 40 degrees for you, and a little square means a right angle (90 Degrees), then 40 + 90 is 130. The interior angles of a triangle always add up to 180, so 180 - 130 is 50. The answer is therefore 50 degrees.
