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

Step-by-step explanation:You need to found the power of 5 so a1=5 you need to find the power of 5
so 136.is 5tothe 10 power so 5x5x5x5x5x5x5x5x5x5
Answer:
-0.8 and -8.2
Step-by-step explanation:
To solve a quadratic you first need to have one side of the equation equal to zero (because x-intercepts are when y is zero).
4x^2 + 24x + 13 = 2x^2 + 6x
2x^2 + 18x + 13 = 0
Then you can use the quadratic formula to solve for x. You will then come to
-18 ± sqrt(220) / 4
This will simplify out (rounding to the nearest tenth) to -0.8 and -8.2
The answer is 24.1 km.
Explanation:
We want to find the diagonal distance between ship 1 and ship 2, which can be done using the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, a^2 + b^2 = c^. Ship 1 will be a, while ship 2 will be b. We now need to plug in the numbers into the Pythagorean theorem equation (Ship 1 is 20 km, and ship 2 is 13.5 km.)
a^2 + b^2 = c^2
(20)^2 + (13.5)^2 = c^2
Now we solve the equation:
1) Find 20 squared and 13.5 squared ( 20 x 20 + 13.5 x 13.5)
400 + 182.25 = c^2
2) Combine like terms (add 400 to 182.25)
582.25 = c^2
3) To isolate c, we need to do the opposite of squaring, which is radical. (The radical of 582.25 is 24.1 rounded to the nearest tenth)
C = 24.1
