The correct answer is 13.86.

In order to find this, we must first note that the tangent of any angle is equal to the opposite side length over the adjacent side length. If we use that formula and the 60 degree angle, we can find y.

Tan(angle) = Opp/Adj

Tan(60) = y/8

8Tan(60) = y

13.86 = y

How to solve (s + 5)(s - 5)

m_a_m_a [10]

$(s+5)(s-5)=s^2-25$

Here, we want to solve an expansion

To get this, we simply multiply the terms in the first bracket with the terms in the second, before we proceed to collect like terms

We have this as follows;

$\begin{gathered} (s+5)(s-5)\text{ = s(s-5)+5(s-5)} \\ =s^2-5s+5s-25 \\ =s^2-25 \end{gathered}$

How do you solve this?

Sholpan [36]

40% of 60 is 24

To convert from percent to decimal, divide the percent without the percent symbol by 100.

so, 40% = 40/100 = 0.4

40% 60 is just 0.4*60 = 24
