Find the common denominator
It is 6
Multiply everything by 6
2/3*(6)= 4g
1/2 *(6)= 3g
14*(6)= 84
4g +3g = 84
7g= 84
g= 12
Complementary angles add up to 90°
and supplementary angles add up to 180°
Add the two angles together
82+98=180
So the measure of these two angles are supplementary
Use the fact that the sum of interior angles of a triangle is equal to 180°.
Hence, the second and the third angles of the given triangle are 180-115/2= 65/2<span>
(32 degrees and 30 minutes).</span>
20x - 15 - 3x - 1 = 15x + 27 + 2x
17x - 16 = 17x + 27
17x - 17x = 27 + 16
0 = 43
Since zero is not equal to 43, this equation has no solution.
Answer: 
Step-by-step explanation:
In order to solve this exercise it is important to remember the multiplication of signs. Notice that:

In this case you have the following expression given in the exercise:

Where the variable is "j".
When you multiply signs, you get:

Now you need to identify that like terms and then you need to add them (or combine them). So, applying this procedure you get that the simplified form of the expression is the shown below:

As you can observe, you get a 2nd degree binomial.
