<h3>1.) Combine x and 3x:</h3>
<em> - We combine the </em>
<em> variables because to get to the end sum of the equation, there can only be 1 variable. So to get the 1, you combine like terms. </em>
<em />
<h3>2.) Add 19 to both sides:</h3>
Cancels Out
- <em></em>
<em></em>
<em> - We do this to get 1 number left over. To do this you do the opposite of what you see. In this case we have a negative 19, so you add 19 on each side of the equals. </em>
<em />
<h3>3.) Divide both sides by 4:</h3>
÷ 
÷ 
<em> - We do this to get x alone. To do this you do the opposite of what you see. In this case we have </em>
<em> which is multiplying, so you divide by 4 on each side. </em>
<em />
So your answer is

Answer:??? sorry i dont know
Step-by-step explanation:
What does "the following" mean ?
Where are the choices ?
Answer:
Yes, Mina is correct
Step-by-step explanation:
Let the triangles be A and B
Given
Triangle A:

Triangle B:

Required
Is Mina's claim correct?
First, we calculate the third angle in both triangles.
For A:


For B:


For triangle A, the angles are: 34, 57 and 89
For triangle B, the angles are: 34, 57 and 89
<em>Since both triangles have the same angles, then by the postulate of AAA (Angle-Angle-Angle), the triangles are similar.</em>
