Du to the triangle is an Equilateral triangle, both angles are equal.
Now we have a straight angle RTU which equals 180 degrees so,
<RTS + <STU = 180
5x + 5x -30 = 180
10x = 210
x = 21
Answer:
<h3>The answer is option F</h3>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To calculate the equation of the line first find the slope
Slope of the line using points
(0 , 0) and (4 , -2) is

Now use the formula
y - y1 = m(x - x1) to find the equation of the line using any of the points
Using point (0,0)
That's

The final answer is
