Answer:
89.0°
Step-by-step explanation:
The segment from the centre of the circle to the chord is a perpendicular bisector, hence
third side of right triangle = 12.7 ÷ 2 = 6.35
The angle subtended at the centre by arc CD is twice the angle subtended by the right triangle at the centre
The triangle from the centre to C is congruent to the triangle from the centre to D
Calculate the angle (Θ ) in the right triangle using the sine ratio
sinΘ = =
Θ = (
) ≈ 44.5°
Hence
measure of CD = 2 × Θ = 2 × 44.5 = 89.0°
Answer:
Reflection, Triangle B is a reflection of A
Step-by-step explanation:
Reflection <em>is when we flip a figure over. </em>
Translation <em>is when we slide a figure in any direction. </em>
Rotation <em>is when we rotate a figure a certain degree around a point. </em>
Dilation <em>is when we enlarge or reduce a figure.</em>
