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:
Step-by-step explanation:
<u>For visible light:</u>
-We can see it. We use visible light to see everything around us, with our eyes at least.
-Visible light has a lower energy than UV light. UV light is what gives us sunburn.
<u>For both:</u>
-They are both forms of electromagnetic radiation (light). They are simply at different energy values and wavelengths. Our eyes can only see the visible part of the spectrum, hence why it is called the "visible" part.
-They are both emitted by the Sun. The Sun lets off many types of radiation.
<u>For UV light:</u>
-UV light is very high in energy relative to visible light. Visible light doesn't give us sunburn, but UV light will. This is what we use in tanning beds.
-UV light cannot be seen with our eyes because it does not fall into the same category as visible light.
23/30 can't be simplified any further because 23 is a prime number.
Answer:
B
Step-by-step explanation:
18 x 2 = 36
20 x 2 = 40
36 + 40 = 76 miles
Answer:
£70
Step-by-step explanation:
There are ten people and each person pays £56 so the total cost will be 10x£56 = £560
The boat will be hired out for the same price (£560) and there are eight people this time, so £560 divided by 8 = £70. This means each person will pay £70.
