Answer:
B. No, the two triangles don't have
corresponding sides marked congruent.
Answer:
Sin A = 20/29
Cos A = 21/29
Tan A = 20/21
Sin C = 21/29
Cos C = 20/29
Tan C = 21/20
Step-by-step explanation:
Sine is opp/hyp, cosine is adj/hyp, and tangent is opp/adj.

Answer:
D. x=15° is the correct answer, hope this helps.
Step-by-step explanation:
The measurement of the outer angle is the semi-difference of the arcs it encompasses.
see the attached figure to better understand the problem
∠x=(1/2)[arc AB-arc CD]
arc AB=40°
Remember that the diameter divide the circle into two equal parts
arc CD=180°-(130+40)°=10°
substitute
∠x=(1/2)[40°-10°]=15°
