Answer:
x = 4
Step-by-step explanation:
a = i-2j
b = 2i-xj
1 = k•2
-2 = k•(-x)
=> 1/2 = k
=> (-2)/(-x) = k
=> 1/2 = (-2)/(-x) => 1/2 = 2/x => x = 4
Answer:
{4H, 4T}
Step-by-step explanation:
The list that contains only the outcomes where the number cube is more than 3 is given below:
Sample space is
= {1,2,3,4}
The results more than 3 is
S = {3}
After this, the sample space i.e. C when the coin is fippled is
C = {H, T}
Here H denotes the Head
T denotes Tail
So, the outcomes would be
= {4} + {H,T}
= {4H, 4T}
If you add them together you will get 11g
The value of csc C in fraction and in decimal form is as follows:
csc C = 5 / 3
csc C = 1.66666666667
Using trigonometric ratio,
secant A = 1 / cos A = hypotenuse / adjacent
Therefore,
sec A = 5/3
sec A = 1 / cos A
cos A = adjacent / hypotenuse
cos A = 3 / 5
A = cos⁻¹ 0.6
A = 53.1301023542
Therefore,
∠A = 53°
∠B = 90°
∠C = 180 - 143 = 37°
cosec C = 1 / sin C = hypotenuse / opposite
cosec C = 5 / 3
