Use trigonometry.
tan30° = perpendicular / base
Here for angle 30° , x is perpendicular while 10 is the base.
tan30° = 1/√3
1/√3 = x/10
x = 10/✓3
By rationalising
x = 10√3/3
Hope This Helps You!
Y intercept is +1
Slope is 1/2
Y= 1/2x + 1
Hello,
Let's calculate ∠O:
∠O=180-2*56=68+
x=90-68=22°
C=2πr and x^2+y^2=r^2
r=4 because of the equation (16)^1/2 is 4
C=8π
