"Supplementary angles" means "angles add to 180 degrees"
So if x is one angle and 67 degrees is the other, and the two angles are supplementary, then x+67 = 180
The answer is choice A
Answer:
a=14, b=58, c=26.5
Step-by-step explanation:
Wat do u need I can help u with anything u need
nCr(20, 2) = 190 ways of selecting 2 from 20
nCr(10, 1) = 10 ways of selecting 1 from 10
To find the over all probability of winning,
Calculate the Harmonic Mean (19) and divide by 2
Equivalent to
1/ (1//190 + 1/10) =9.5
So the probability is 1/9.5 = 2/19.
Yes it is true:
(1 - cos^2 x) = sin^2 x Sqr.(1 - cos^2 x) = sin x and (-sinx) True, since sin x negative. Also, x terminates in quadrant 3 and 4. Hope this is helpful
