The answer is C because it shows you
Answer:
The measure of m∠KNY is;
(D) 105°
Step-by-step explanation:
From the diagram, we have;
The given angle at the circumference = The The angle the arcs makes at the center of the circle
From circle, theorem, angle subtended at the center = Twice the angle subtended at the circumference
Therefore;
Angle ∠D and angle ∠Y = 90°/2 = 45°
Angle ∠O and angle ∠K = 60°/2 = 30°
From angle summation theorem, we have;
m∠KNY + ∠K + ∠Y = 180° (The sum of the interion angles in ΔYNK
∴ m∠KNY = 180° - (∠K + ∠Y)
Plugging in the known values of ∠K and ∠Y gives;
m∠KNY = 180° - (30° + 45°) = 105°
m∠KNY = 105°.
Answer:
See below
Step-by-step explanation:
a. How fast does the plane fly during the first leg of the trip?
b. How fast does the plane fly during the last leg of the trip?
c. What system of equations might be helpful in this scenario?
<u>s - speed of the plane, w - speed of the wind, equations:</u>
d. Solve this system of equations using the best method.
Add the equation together to get:
- 2s = 1100 ⇒ s = 550 mph
- w = 550 - 430 = 120 mph
e. How fast is the wind?
f. How fast does the plane fly without any wind?
4xy-3y=12
y(4x-3)=12
y=12/(4x-3)
