j = 10

Step-by-step explanation:

use the definition of tangent of an angle:

tan 60 = opp/hyp = (10√3)/j

Solving for j,

j = (10√3)/tan 60

But tan 60 = √3 so we can write j as

j = (10√3)/√3

= 10

the ratio of children to adults is two to seven. there are 100 more adults than children. how many adults and children are in th
Alex Ar [27]

Answer: There are 140 adults and 40 children.

Step-by-step explanation:

Let 2x = Number of children

7x = Number of adults.

As there are 100 more adults than children.

That means, 7x-2x = 100

\Rightarrow\ 5x=100\\\\\Rightarrow\ x=\dfrac{100}{5}\\\\\Rightarrow\ x=20

Number of children =  2 (20)=40

Number of adults = 7(20) = 140

Hence, there are 140 adults and 40 children.

It is important to know that probabilities are defined insed the range [0,1], which means they cannot be outside that set of values.

<h2>Hence, -0.56, square root of 2, 1.23, and 5/3 can't be probabilities because they are outside the range of values.</h2>
