Answer:
x=8
Step-by-step explanation:
(3x-8)/1=4x/2. 3x-8=2x, x=8
Diameter of the circle =4+4=8
Area of semicircle =8 pi
Area of triangle= 1/2*4*8=16
Area of the shaded area=8pi -16=2.9 pi approximately 3pi
C I guess
I don’t understand
Starting time=1:45
ending time =3:30
add to get=4:75
one hour=60 minutes
75-60=15
answer=5:15
The following expressions (1+cosβ)(1−cosβ)sinβ is equivalent to sin³β
<h3>What are Trigonometric Ratios ?</h3>
In a Right angled triangle , trigonometric ratios can be used to determine the value of angles and sides of the triangle.
The trigonometric expression given in the question is
(1+cosβ)(1−cosβ)sinβ
(a+b)(a-b) = a² - b²
( 1 - cos²β)sinβ
By the trigonometric Identity
1-cos²β = sin² β
sin² β x sin β
sin³β
Therefore Option B is the correct answer.
