Answer:
Maybe 180° -50° = 130°
So I think x= 130°
Step-by-step explanation:
My opinion though
Answer:
15cm
Step-by-step explanation:
a^2+b^2=c^2
12^2+9^2=c^2
144+81=c^2
c^2=225
c=15
Answer: y = x^2 - 11x + 24
Step-by-step explanation:
Answer:
Radius of the Earth is 3978.8 Miles
Circumference of the Earth is 25000 Miles
Step-by-step explanation:
The angle of the sun shone at an angle of 7.2° to the zenith
This means that the angle of the sector of the circle is 7.2° (θ)
S = Length of the sector of the circle = 500 miles
r = radius of earth
Converting 7.2° to radians


∴ Radius of the Earth is 3978.8 Miles

∴ Circumference of the Earth is 25000 Miles
