Answer:
AC = 5 and BC = 5√3
Step-by-step explanation:
Given:
m<A = 60°
m<B = 30°
AB = 10
Required:
AC and BC
Solution:
Recall, SOH CAH TOA
✔️Find AC:
Reference angle (θ) = 30°
Hypotenuse = 10
Opposite = AC
Apply SOH:
Sin θ = Opp/Hyp
Substitute
Sin 30° = AC/10
10*Sin 30° = AC
10*½ = AC (sin 30° = ½)
5 = AC
AC = 5
✔️Find BC:
Reference angle (θ) = 60°
Hypotenuse = 10
Opposite = BC
Apply SOH:
Sin θ = Opp/Hyp
Substitute
Sin 60° = BC/10
10*Sin 60° = BC
10*√3/2 = BC (sin 60° = √3/2)
5*√3 = BC
BC = 5√3
Answer:
<em>Circle Equation: ( x - 3.8 )^2 + ( y - 7.8 )^2 = 25/36</em>
Step-by-step explanation:
* Knowing a circle equation is in the format (x – h)^2 + (y – k)^2 = r^2, with the center being at the point (h, k) and the radius being "r" *
Let us substitute values into this equation; provided ( 3.8, 7.8 ) is the center:
( x - 3.8 )^2 + ( y - 7.8 )^2 = r^2,
Now substitute value of r, or rather the radius 5/6:
( x - 3.8 )^2 + ( y - 7.8 )^2 = ( 5/6 )^2 ⇒
<em>Circle Equation: ( x - 3.8 )^2 + ( y - 7.8 )^2 = 25/36</em>
