Answer:
The correct answer is first option
X = 34.61
Step-by-step explanation:
<u>Points to remember</u>
<u>Trigonometric ratios</u>
Sin θ = Opposite side/Hypotenuse
Cos θ = Adjacent side/Hypotenuse
Tan θ = Opposite side/Adjacent side
From the figure we can see that a right angled triangle with base x and hypotenuse = 81.9.
One angle = 65°
To find the value of x
We have Cos θ = Adjacent side/Hypotenuse
Cos 65 = X/81.9
X = 81.9 * Cos 65
= 81.9 * 0.4226
= 34.61
Therefore X = 34.61
The correct answer is first option
845* (100-62)%
=845*38%
=845*38/100
=32110/100=321,1

Answer:
The correct answer is option A.
Step-by-step explanation:
Hi! I don't know why I am not getting any brainliest answer. So if you are kind enough could you please mark me as the brainliest answer and please follow me also.
X = weight of each bag of flour
30x + 4*0.75 = 42.6
30x + 3 = 42.6
30x = 39.6
x = 39.6/30
x = 1.32kg
