Answer:
Denote O as center of circle, draw OA, OC.
As property of tangent line from outside of circle (angle OAD = angle OCD = 90 deg):
=> AOC + D = 180
Moreover, angle AOC = 2 x angle B = 2 x 65 = 130
=> D = 180 - 130 = 50 deg
Hope this helps!

10! If you use the trapezoid area formula and plug in the known values, just solve for h(height)
Answer:
Step-by-step explanation:
Total peanuts = 5/6pounds
They ate = 3/4 of the peanut
= 3/4 × 5/6 = 5/8pounds
They eat 5/8 pounds
Amount left = 5/6 - 5/8
= (20 - 15)/24
= 5/24pounds
Jesus had 5/24 pounds of peanuts left
Answer:
The positive solution is 2.4.
Step-by-step explanation:
The given functions are
It is given that
The quadratic formula:
Therefore the positive solution is 2.4.
<span>A would be 6/7 x 28kg = 24 kg
B would be 4/7 x 28kg = 16 kg
so the difference of the masses is 24 - 16 = 8kg</span>
