Answer:
-60
Step-by-step explanation:
5-5=0
12*5=60
0-60=-60
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
Because he divided his cake into 6 equal pieces, we can represent the eaten and remaining amounts with fractions.
Remember that a fraction is the ratio of number of pieces over the total pieces.
So, we need to figure out how much cake needs to be subtracted.
We know his sister ate 1/6 of the cake and he ate 3/6 of the cake. We can add these fractions together because they have common denominators.
3/6+1/6=4/6
So, we need to subtract 4/6 from the whole:
6/6-4/6=2/6, so 2 slices out of the 6 remain.
Answer:
It is true. They are the sides of a right angled triangle.
Step-by-step explanation:
According to pythagoras theorem,
h² = p² + b²
where h is the largest side.
So,
13² = 12² + 5²
169 = 144 + 25
169 = 169
This is true.
