Given formula:

To solve for 
In order to solve for
we will try to isolate
on one side of the equation.
Steps to isolate
.
1) Multiplying both sides by
to remove fractions.


2) Subtracting both sides by 


3) Subtracting both sides by 


Thus, we successfully isolated
on one side. The formula for
can be given as:
∴ 
Answer:
102
Step-by-step explanation:
it is an isosceles triangle as two sides are equal i.e 3.3 so angles opposite to equal sides are also equal so 39 plus 39 plus x = 180°
78 plus x =180
x=180-78
x=102°

Answer:
B. 
Step-by-step explanation:
Let p be number of points Michael needs to score in 2nd game to catch up.
We have been given that Janet scored 200 and 400 points in the first 2 rounds of a computer game. So the total points scored by Janet in two games will be:
points.
We are also told that Michael had scored 250 points in the first round and he want to get the same total score as Janet.
So we can find the number of points Michael needs to score to catch up Janet by subtracting the number of points scored by Michael in 1st game from total number of points scored by Janet in two games. We can represent this information in an equation as:

Therefore, the equation
will help Michael to find the number of points he need to catch up Janet and option B is the correct choice.
