Answer:
The measure of a minor arc is less than 180° , and equal to the measure of the arc's central angle . A major arc is the longer arc connecting two endpoints on a circle. The measure of a major arc is greater than 180° , and equal to 360° minus the measure of the minor arc with the same endpoints.
Answer:
When solving a simple equation, think of the equation as a balance, with the equals sign (=) being the fulcrum or center. Thus, if you do something to one side of the equation, you must do the same thing to the other side. Doing the same thing to both sides of the equation (say, adding 3 to each side) keeps the equation balanced.
Solving an equation is the process of getting what you're looking for, or solving for, on one side of the equals sign and everything else on the other side. You're really sorting information. If you're solving for x, you must getx on one side by itself.
Addition and subtraction equations
Some equations involve only addition and/or subtraction.
Example 1
Solve for x.
x + 8 = 12
To solve the equation x + 8 = 12, you must get x by itself on one side. Therefore, subtract 8 from both sides.

Answer:
d = 2750/Cos 48
Step-by-step explanation:
We need the value of the angle from the vertical axis
90 - 42 = 48°
We are trying to find the distance d which is the Hypotenuse of the right angled triangle formed.
The relationship between the adjacent and hypotenuse is help by the cosine of the angle between them
such that
Cos 48 = Adj/Hyp
Cos 48 = 2750/d
d Cos 48 = 2750
d = 2750/Cos 48
