Answer:
The correct answer is option b. Sin or csc
Step-by-step explanation:
<u>Trigonometric ratios</u>
Sinθ = Opposite side/Hypotenuse, Cosec = 1/Sinθ
Cosθ = Opposite side/Hypotenuse , Secθ = 1/cosθ
Tan θ = Opposite side/Adjacent side, cotθ = 1/Tan θ
From the figure we can see a right angled triangle RST,
Right angled at R
<u> To find the value of TS</u>
We have m< S=27º and TR=7
Sin S = TR/TS
TS = Sin S * TR
Cosec = 1/Sinθ
Therefore the correct answer is option b
<u>Answer:</u>
The correct answer option is B. equal.
<u>Step-by-step explanation:</u>
In a symmetrical distribution the mean, median, and mode are equal.
In any distribution which is symmetric, half of its curve is the mirror image of the other half. The pull remains same on each side and the frequencies are also symmetrically distributed.
Therefore, mean, median and mode all fall at the middle as one side balances the other sides.
1. 3(p+q)=p
3p+3q=p; 3p-p=3q; 2p=q so p=q/2
2. 4a=2b-7
2b=4a+7 so b=(4a+7)/2
when a=3 , b=(12+7)/2=19/2=9.5
3. d=rt; r=d/t
4.( 2x15)+(2xwidth)=90
2x width=90-30
width =60/2=30
