Answer: 'X' = 24 degrees

Step-by-step explanation:

5 times 'X' = 120 degrees (because the formula is base times height divided by 2).

120 divided by 5 = 'X'

= 24

'X' = 24 degrees

What is the truth value for the following conditional statement? p: true q: false ∼q → ∼p T F → F T T → F F T → T T F → T

arsen [322]

Answer:

False F

Step-by-step explanation:

You are given two statements p and q. For these two statements fill in the logic table:

$\begin{array}{ccccccccc}p&|&q&|&\sim p&|&\sim q&|&\sim q\rightarrow \sim p\\T&|&T&|&F&|&F&|&T\\T&|&F&|&F&|&T&|&F\\F&|&T&|&T&|&F&|&T\\F&|&F&|&T&|&T&|&T\end{array}$

So, when p is true and q is false, statement $\sim q\rightarrow \sim p$ is false.

Can somebody please help me? (PreCalc

$\csc\theta=\dfrac1{\sin\theta}=\dfrac{\sqrt{17}}}4\implies\sin\theta=\dfrac4{\sqrt{17}}$

Recall that $\sin^2\theta+\cos^2\theta=1$ , which means

$\cos\theta=\pm\sqrt{1-\sin^2\theta}=\pm\sqrt{1-\dfrac{16}{17}}=\pm\dfrac1{\sqrt{17}}$

Since $\tan\theta=\dfrac{\sin\theta}{\cos\theta}>0$ , and $\sin\theta>0$ , it follows that $\cos\theta>0$ too, so you take the positive root:

$\cos\theta=\dfrac1{\sqrt{17}}$

Therefore

$\cot\theta=\dfrac{\cos\theta}{\sin\theta}=\dfrac{\frac1{\sqrt{17}}}{\frac4{\sqrt{17}}}=\dfrac14$

Step-by-step explanation:

We assume your "natural numbers" are <em>positive integers</em>. (Some authors also include zero.)

n(B) = 5

n(U) = 20

n(B') = 20 -5 = 15
