Answer:
x = 49
Step-by-step explanation:
The central angle AOB is equal to the measure of the arc that subtends it, so
∠ AOB = 82°
OA = OB ( both radii of the circle ), then Δ AOB is isosceles and the 2 base angles are congruent, then
x = =
= 49
Answer:
Step-by-step explanation:
Let use the basic function of sin first.
Since the midline is 1 and the max point is 5, the amplitude is 4.
The midline is 1 since the midline is at 0,1.
Since we know the distance of the max and midline x values
We can multiply that by 4 to find our period.
Use the equation 2pi/b to find the b we would use in our equation.
The answer is
so our equation is
