1) By the inscribed angle theorem, 
2) By the inscribed angle theorem, arc RT measures twice 63 degrees, or 126 degrees.
the answer is d thats what im choosing because i recall doing a similar problem to this
Y - 2 = -3x + 12
3x + y = 14
Answer:
35
Step-by-step explanation:
sin is opposite over hypotenuse
sin x = 8/14
The equation of line is:

Further explanation:
Given
y = 2x + 2
Comparing it with standard form:
y=mx+b
Let m1 be the slope of given line

We know that product of slopes of two perpendicular lines is -1
Let m2 be the slope of second line

Putting the value of m2 in standard form

To find the value of b, putting (6,3) in equation

Putting the values of b and m, we get

The equation of line is:
