Answer:
c² = 3² +6² - 2⋅3⋅6⋅cos 60
c = 27ft
Step-by-step explanation:
Since the angle is located in between the sides of the sides, we will use the cosine rule to get the unknown sides
Let c be the missing sides
According to the cosine rule;
c² = a²+ b² - 2abcosC
c² = 3² +6² - 2⋅3⋅6⋅cos 60
c² = 9 + 36 - 36cos60
c² = 45 - 36cos60
c² = 45 - 36(0.5)
c² = 45 - 18
c² = 27ft
Hence the missing attribute is 27ft and the required expression is c² = 3² +6² - 2⋅3⋅6⋅cos 60
Answer:
In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x⁻¹, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a/b is b/a. For the multiplicative inverse of a real number, divide 1 by the number.
Step-by-step explanation:
To find the reciprocal, divide
1
by the number given.

Answer:
51
Step-by-step explanation:
area = pi x r^2
so
3.14 x 25
around 76
so
2/3 of 76

Answer:
Last option is the correct answer.
Step-by-step explanation:
Total number of movies = 9+7+4=20
The total number of combinations of choosing 3 movies from total 20 is represented by 20C3. Then there are 9 action movies and we're choosing 3, the number of combinations will be 9C3,
Now, the probability of choosing all action movies will be:
As we know that probability of something which is not happening is given as : 1 - probability of something happening, so the probability of not choosing all action movies is given by: 
Hence, option D or last option is the right one.
Answer:
<h2>x = 29°</h2>
Step-by-step explanation:
From the question the angles lie on a straight line which means that the sum of their angles add up to 180°
Since angles on a straight line add up to 180°
To find the value of x add up all the angles and equate it to 180 to find x
That's
x + 4 + 147 = 180
x + 151 = 180
x = 180 - 151
We have the final answer as
<h3>x = 29°</h3>
Hope this helps you
