angle C = 90°
angle O = 67°
Step-by-step explanation:
Line AC is tangent to the circle at point C. Since OC is the radius, this means that OC is perpendicular to AC. Since the sum of the interior angles of a triangle is 180°, then
23° + 90 + angle O = 180°
or
angle O = 67°
-1 + x + 3 -> x+2
ANSWER : x + 2
Plug in the x+3 for y.
8x-x+3=12
7x=9
X=1.3
Then, y= -0.25
I think you need to explain more for one to answer it.
Please give more details and I'll try to help (if this is meant to be a question)
