Answer:
A) 21.02°
B) 26.74°
C) 22.79°
D) DNE
Step-by-step explanation:
We can solve the equation for the angle:
D = 672·sin(2θ)
D/672 = sin(2θ)
arcsin(D/672) = 2θ
θ = arcsin(D/672)/2
A) For D = 450, θ = arcsin(450/672)/2 = 21.0198° ≈ 21.02°
B) For D = 540, θ = arcsin(540/672)/2 = 26.7363° ≈ 26.74°
C) For D = 480, θ = arcsin(480/672)/2 = 22.7923° ≈ 22.79°
D) For D = 720, θ = arcsin(720/672)/2 = DNE
Answer:
the 1 is the hundred thousand place and the 7 is in the ten thousand place
Step-by-step explanation:
Answer:
The last option.
Step-by-step explanation:
Well, in this case, the a-value is 1, b-value is -9, and c-value is 5.
You would have -(-9) plus or minus the square root of ((-9)^2) - 4 * 1 * 5, divided by 2 * 1.
That would be [9 plus or minus sqrt(81 - 20)] / 2
= [9 plus or minus sqrt(61)] / 2
That is the last option.
Hope this helps!
