90

Find the segment length indicated. Assume that lines which appear to be

tangent are tangent.

Calculate the value for ?.
Tangent to Circles - Find Segment Length
Hypotenuse
Answer (round to nearest tenth): X =
  9.12 + x2 = 10.92
-9.12            -9.12
x2 = 10.99.12
Tips for solving for angles:•Identify the hypotenuse.•Use Pythagoreans theorem.Sometimes only a part of a segment  needs to be calculated.
x2 = 10.99.12
x2 = 118.81 - 82.81
x2 = 36
x = 6.0
Hypotenuse(call it "c")
Calculate the value for ? which is only PART of the hypotenuse.

Find the segment length indicated. Assume that lines which appear to be

tangent are tangent.

Answer (round to nearest tenth): X =
9.92 + 13.22 = c298.01 + 174.24 = c2
272.25 = c2 16.5 = c
Tips for solving for angles:•Identify the hypotenuse.•Use Pythagoreans theorem.Sometimes only a part of a segment  needs to be calculated.
Tricky Part:
x = c - radius
x = 16.5 - 9.9
x = 6.6
