Answer:
x = 130 degrees
Step-by-step explanation:
angle OAC = angle OBC = 90 degrees (angle between tangent and radius = 90 degrees)
This is quadrilateral and we know that quads = 360 degrees
So...
x + 90 + 90 + 50 = 360
rearrange
x = 130 degrees

Formula
--------------------------------------------------
Area of circle = πr²
--------------------------------------------------
Find radius
--------------------------------------------------
πr² = 75
r² = 75 ÷ π
r² = 23.87
r = √23.87
r = 4.89 cm (nearest hundreds)
--------------------------------------------------
Answer : radius = 4.89cm
