Answer:
height = 23 ft , Width=43ft
Step-by-step explanation:
Step one:
Given data
Given data
Diagonal = 66ft
Aspect ratio= 19:10
From the formulas below, we can find the dimensions of the theater screen
height = diagonal / √ (AR²+1)
where AR is the aspect ratio
Step two:
height = 66 / √ ((19/10)² + 1) =
height = 66 / 2.9
height = 23 ft
Step three:
Also,
width = AR * height
width = (19/10) * 22.75
width =1.9* 22.75
Width=43ft
Answer:
That is truth
Step-by-step explanation:
Remember that sin(x-y)= sin(x)*cos(y) + sin(y)*cos(x)
Lets evaluate x=360, y=theta
sin(360-theta)=sin(360)*cos(theta) -sin(theta)*cos(360)
Also, remember that sin(360)=sin(0)=0
Cos(360)=cos(0)=1
Thus
Sin(360-theta)=-sin(theta)
A=r^2pi is the area of a circle
