Answer:
Angle ECA=68°
Explanation:
To solve, set the two angles equal to each other.
14x-2=12x+8
Now, we need to make the x's go to one side of the equation. This is because we need the x's to equal something. Otherwise, we can't solve. To do this, I am going to move 12x to the right. Remember, if a number is positive on one side, it will be negative when you move it to the other.
2x-2=8
Now, we need to add two to both sides.
2x=10
Now divide both sides by 2.
x=5
Now to solve, plug in 5 for x.
14(5)-2= ?
70-2=68

Explanation:
im guessing im sorry if im wrong
A geographic coordinate system<span> or a GCS uses a three-dimensional spherical surface to define certain locations on earth. Also, a GCS is often mistakenly called a datum, but a datum is just one part of a GCS.
Finally, a GCS includes a prime meridian, </span><span>an angular unit of measure, </span>and a datum :)
Answer:
<u>69 miles (111 kilometers)</u>
Explanation:
- Each degree of latitude on the surface of the earth is about 68 miles away from each other this is caused due to the axial tilt and elliptical shape or bulge of the planet.
- From 68.703 miles (110.567 km) at the equator to 69.407 (111.699 km) at the poles. Since the longitude varies from equator to poles the poles see most of the variations.
- For calculating the degree of longitudes first convert latitude into decimal ~ 37.26 then convert your decimal into radians ~ 0.650. Take out the cosine in radians ~ 0.795 Thus one degree of Longitude = ~0.795 * 69.17 = ~ 55.05 miles

Answer:
C. 2π cm
Explanation:
Measure of the length of arc(QR) = θ/360 × 2πr
Where,
θ = 60°
r = 6 cm
Plug in the values
Measure of the length of arc(QR) = 60/360 × 2 × π × 6
= 1/6 × 12 × π
= 2 × π
= 2π cm
