Step-by-step explanation:
a)
Two of the three interior angles are known. Both are equal to 55°. This can be seen by looking closely at the picture. To find the third angle subtract the other two from 360°

b)
Do the same thing only afterward subtract the third angle from 180 to find the supplementary angle

Answer:
It's 1/4
Step-by-step explanation:
It's closer to 0 than the other fractions
Answer:
27. chord
28. radius
29. diameter
30. secant
31. tangent
32. secant
Step-by-step explanation:
I guess thats the correct answer
Use trigonometry.
sinQ = 14/50 = 0.28
-> angle Q = sin^-1(0.28) = approx 16 degrees
-> cosQ = A/H -> cos16 = PQ/50
=> PQ = 50*cos16 = approx 48.06
So yea.
