See below for the proof that the areas of the lune and the isosceles triangle are equal
<h3>How to prove the areas?</h3>
The area of the isosceles triangle is:
Where r represents the radius.
From the figure, we have:
So, the equation becomes
Evaluate
Next, we calculate the length (L) of the chord as follows:
Multiply both sides by r
Multiply by 2
This gives
The area of the semicircle is then calculated as:
This gives
Evaluate the square
Divide
Next, calculate the area of the chord using
Recall that:
Convert to radians
So, we have:
This gives
The area of the lune is then calculated as:
This gives
Expand
Evaluate the difference
Recall that the area of the isosceles triangle is
By comparison, we have:
This means that the areas of the lune and the isosceles triangle are equal

Yeah that's right I'm pretty sure that's the work u do so u r not wrong ok so relax
Answer:
∠ EFH = 112°
Step-by-step explanation:
∠ ACD and ∠ EFH are Alternate exterior angles and are congruent, thus
11x - 20 = 9x + 4 ( subtract 9x from both sides )
2x - 20 = 4 ( add 20 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12
Thus
∠ EFH = 11x - 20 = 11(12) - 20 = 132 - 20 = 112°
Answer:
the x intercept is -4
Step-by-step explanation:
to find the x intercept, set y = 0 and solve for x
y = 5x+20
0 = 5x+20
subtract 20 from each side
-20 = 5x +20 -20
-20 = 5x
divide each side by 5
-20/5 = 5x/5
-4 =x
