Tangent always meets radius at 90° angle.
Angle ABC = 90° so Pythagoras' theorem applies.
r² + 4² = (r+2)²
r² + 16 = r² + 4r + 4
12 = 4r
r = 3
Answer:
x = 8
Step-by-step explanation:
For the triangles to be congruent, then the legs
ED = AB, that is
4x + 2 = 34 ( subtract 2 from both sides )
4x = 32 ( divide both sides by 4 )
x = 8
