Exercise 32 Page 769

If a line is tangent to a circle, then the line is perpendicular to the radius at the point of tangency.

66

Practice makes perfect

If a line is tangent to a circle, then the line is perpendicular to the radius at the point of tangency.

Finally, to find the value of x, recall that the sum of the angle measures in a quadrilateral is 360.

x + 90 + 90 + 114 = 360

Add terms

x + 294 = 360

LHS-294=RHS-294

x = 66
