Answer:
Definition of Midpoint
Step-by-step explanation:
Say RS is 20(as an example), that would make RT 10 and TS 10. The two halves of the midpoint are congruent.
Answer:
∠ ABC = 22°
Step-by-step explanation:
OA = OB ( radii of circle )
Then Δ OAB is isosceles with base angles congruent , that is
∠ OBA = ∠ OAB = 17x
The sum of the 3 angles in the triangle sum to 180°
17x + 17x + 11x = 180
45x = 180 ( divide both sides by 45 )
x = 4
Then
∠ OBA = 17x = 17(4) = 68°
BC is a tangent so ∠ OBC = 90°
∠ ABC = 90° - ∠ OBA = 90° - 68° = 22°
Answer:
h = -4

Answer:
An expression equivalent to 5 (x + 10) is <em>5x + 50.</em>
