Step-by-step explanation:
Answer: 15.59 or 9√3
Step-by-step explanation:
We can use the Pythagorean Theorem to calculate the third side.
c² = a² + b² In a 30 60 90 Triangle, the hypotenuse is twice the length of the short leg of the right angle.
c is the hypotenuse. a is the short leg
18² = 9² + b²
324 = 81 + b² Subtract 81 from both sides.
324 - 81 = b² becomes b² = 243 Take the square root of both sides
b = 15.5884 . This can be rounded to 15.59 or 15.6 depending on significant digits or amount of precision required.
The proportions of the sides of the 30 60 90 triangle can also be used:
2² = 1² + b²
4 = 1 + b²
3 = b²
√3 = b
You can always multiply the length of the short leg by √3 to get the length of the side opposite the 60° angle
The equation for this statement:
2x – 14 = 6
=> 2x = 6 + 14
=> 2x = 20
=> x = 20/2
=> x = 10
In 7 minutes, the clock has rotated 42 degrees
<u>Solution:</u>
Given, A clock is constructed using a regular polygon with 60 sides.
The polygon rotates every minute.
As there will be 60 minutes in clock, and this clock has 60 sides, each minute represents a side.
Now we know that, in a clock, 1 hour = 60 minutes
60 minutes = 360 degrees
Then, 7 minutes = “n” degrees
So, by criss cross multiplication,
Hence, in 7 minutes, the clock has rotated 42 degrees
