Answer: x = 143 degrees, y = 37 degrees and z = 143 degrees
Step-by-step explanation: First of all, looking at the line where x is situated,
37 + x = 180 {Sum of angles on a straight line equals 180}
Subtract 37 from both sides of the equation
x = 143
Next, looking at the line where y is situated, we observe that angle y is opposite of angle 37. Opposite angles are equal, therefore
y = 37
Alternatively, since angles x and y lie on the same line, and x has been calculated as 143, then
y + x = 180
y + 143 = 180
Subtract 143 from both sides of the equation
y = 37
Also looking at the line where angle z is situated, angle z is opposite angle x. Opposite angles are equal. Therefore z = 143.
Alternatively angle z and angle 37 lie on the same line. Therefore,
z + 37 = 180
Subtract 37 from both sides of the equation
z = 143
So all three variables are
x = 143, y = 37 and z = 143
<h2>(x, y) = (21/13 , 84/13)</h2>
Step-by-step explanation:
x + 3y = 21
- 4x + y = 0
y = 4x
<h2>_____________</h2>
x + 3y = 21
x + 3(4x) = 21
x + 12x = 21
13x = 21
x = 21/13
y = 4x
y = 4 (21/13)
y = 84/13
(x, y) = (21/13 , 84/13)
