Question

O is the center of the circle. Assume that lines that appear to be tangent are tangent. What is the value of x?
30.5
119
58
61

Answer 1

Well, the statement that the line is tangent to the circle is a way to tell you that the other angle is basically 90 degrees. So if you have 2 angles known, you find the 3rd angle by knowing that the angles of a triangle add up to 180 degrees.

Answer 2

so it 30.5 then

Answer 3

\[90{}^{\circ}-29{}^{\circ}=61{}^{\circ} \]
