Answer:
First drawing - answer is: D: DG, FG and DE
Second drawing - answer is: π (pi)
Third drawing - answer is: 70° ( If you mean on measure of central angle which is corresponing to the arc CB)
Fourth drawing - answer is: y=55° ( If you mean that the value of angle ∠AOB=70° )
Step-by-step explanation:
For the second drawing
arc AB = (r · π / 180) · α = (3 · π/180) · 60 = (180 · π) / 180 = π
For the third drawing
∠CAB is peripheral angle of the central angle ∠CFB.
∠CFB= 2·∠CAB= 2· 35° = 70°
Good luck!!!
Answer:
The value of x = 6
Step-by-step explanation:
Given
To determine
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
here:
so substitute (x₁, y₁) = (x, -4)
, (x₂, y₂) = (2, 8) and m = -3
m = [y₂ - y₁] / [x₂ - x₁]
-3 = [8 - (-4)] / [2 - x]
-3 = [12] / [2-x]
-3 (2-x) = 12
-6+3x = 12
3x = 12+6
3x = 18
divide both sides by 3
3x/3 = 18/3
x = 6
Therefore, the value of x = 6
Answer:
D. 
Step-by-step explanation:
Area of sector of a circle is given as θ/360*πr²
Where,
r = radius = 12 cm
θ = 56°
Use 3.14 as π
Plug in the values into the formula and solve
Area of the sector ABC = 
The answer is D
Answer:
points (8, 0) and (3, 0)
Step-by-step explanation:
Here we're being asked to find the roots of this quadratic equation.
Set f(x) = 3(x² - 11x + 24 = 0.
This factors into f(x) = 3(x - 8)(x - 3) = 0.
Then x - 8 = 0 and x - 3 = 0, yielding x = 8 and x = 3. These correspond to the points (8, 0) and (3, 0).
