Max points

so previously i answered,

(a) start by writing the equation of the circle. (recall that the general form of a circle with the center at the origin is x2 + y2 = r2. (10 points) x^2 + y^2 = 30^2

and

(b) now solve this equation for y. remember the roller coaster is above ground, so you are only interested in the positive root. (10 points) y = √(900 - x^2)

now i have to solve this in the image attached,

any ideas?

a chart a graph or even a powerpoint will work

Step-by-step explanation:

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
