Please i need help ASAP please no links. A chord is units from the center of a circle. The radius of the circle is units. What is the length of the​ chord?

Draw a line from the center of the circle to the chord to form a right triangle.

The radius (20) forms the hypotenuse of the right triangle and distance from the center to the chord (16) forms a leg.

Use the Pythagorean Theorem to find the length of the other leg x (which would be 1/2 the length of the chord):

x^2 + 16^2 = 20^

x = 12

So the entire chord length = 12 * 2 = 24 units

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°
