Answer:
24.8
Step-by-step explanation:
We will have to use trigonometry here to find the value of x. The first thing we can see is that we need to work out the hypotenuse. We need to chose whether to use Sin, Cos or Tan. We do that by look at the sides .
→ 'x' is the hypotenuse
→ 12 is opposite
→ The adjacent is the side that doesn't have a numerical value to we look for a formula triangle without adjacent in it
Tan = Opposite ÷ Adjacent
Sin = Opposite ÷ Hypotenuse
Cos = Adjacent ÷ Hypotenuse
We can see the Sin formula has no adjacent in it so we use that formula. However we want to work out the hypotenuse so we have to rearrange the sin formula to get hypotenuse as the subject so
Sin = Opposite ÷ Hypotenuse
Hypotenuse = Opposite ÷ Sin
→ Let's substitute in the values
Hypotenuse = 12 ÷ Sin(29)
Hypotenuse = 24.7519841
So the value of x is 24.8 to 1 decimal place
Given:
The square box.
To find:
The fraction of colored part of the square.
Solution:
From the given box it is clear that,
Total number of small squares = 100
Number of colored squares = 0
So, the fraction of colored part of the square is
Therefore, the fraction of colored part of the square is .
Answer:
Step-by-step explanation:
Let 'm' denotes the mass of helicopter, 'g' denotes the gravity and 'a' denotes the acceleration.
We know that
Put
So,
Also, as per Newton's second law,
Put
So,
We know that the lift force is the sum of the gravitational force and the force of motion.
Answer:
-2, -2/1
Step-by-step explanation:
If you start from the point in the quadrant II, you go 1 to the right and 2 down and there will be another point on the line. For example, from point (-3, 6) when you go 1 right and 2 down the next point is (-2, 4).
A of n = 2n^2 - 3
the nth term = 2 times n to the power of 2 minus 3
