Answer two questions about Equations A and B: A. 5x – 2 + x= x- 4
B.5x+ x= x- 4
1) How can we get Equation B from Equation A?
Choose 1
A)Add/subtract a quantity to/from only one side
B)Add/subtract the same quantity to/from both sides
C)Rewrite one side (or both) using the distributive property
D)Rewrite one side (or both) by combining like terms

2)Based on the previous answer are the equations equivalent? In other words, do they have the same solution

A)yes
B)no

A and D

Are the more likely options to apply

Shania is correct.

Step-by-step explanation:

For a right angled triangle, given two sides and an angle, we can use the sine rule or the various trigonometry identities to solve the triangle;

a/sin A = b/sinB

and

sin (angle) = opposite side/hypotenuse

cos (angle) = adjacent side/hypotenuse

tan (angle) = opposite/ adjacent

assuming a is the opposite side of angle A and b is also opposite of angle B

Otherwise, the only way to solve a triangle given two sides only is by the use of the Pythagoras theorem.

Hence, Shania is correct.
