Answer: Third option
Step-by-step explanation:
One of the ways of solving a system of equations is by equating the equations and solving for one of the variables.
In this case we have the system:
Note that if is equal
and also
equals
Then logically must be equal to
.
We write equality.
Then the correct answer is the third option.
We can also solve for the variable x
Based on the calculations, the value of x in this rhombus is equal to: B. 55.
<h3>How to determine the value of x?</h3>Since the opposite angles in a rhombus are always congruent, the sum of each angle in any rhombus must be equal to 360 degrees.
From the image of the rhombus, we can deduce the following parameters:
Adjacent angles = 2x + 20 and 50 degrees.
Opposite angles = 2x + 20 and 50 degrees.
Adding the angles, we have:
2x + 20 + 2x + 20 + 50 + 50 = 360
4x + 140 = 360
4x = 360 - 140
4x = 220
x = 220/4
x = 55°
