Solve for an angle in right triangles

madreJ [45]

The angle of B is 56.2 degrees

<em><u>Solution:</u></em>

Given is a right angled triangle ABC

From given figure,

AB = 9

CB = 5

We have to find the angle of B

Let the angle of B be $\theta$

By definition of cosine,

$cos \theta = \frac{adjacent}{hypotenuse}$

Here, adjacent = CB and hypotenuse = AB

Therefore,

$cos \theta = \frac{5}{9}\\\\cos \theta = 0.556$

Taking cos inverse on both sides,

$\theta = cos^{-1}(0.556)\\\\\theta = 56.22038005 \approx 56.22$

Thus the angle of B is 56.22 degrees

Which number line shows the solution set for |m| = 4

Margaret [11]

Answer:

Last choice that shows points on +4 and -4 is the correct graph.

Step-by-step explanation:

We have been given equation $|m|=4$ . Now we need to find out which of the given number lines shows the corret solution set for $|m|=4$ .

We know that $|x|=a$ can be broken into two parts as:

$x=+a$ and $x=-a$

Same way we can break $|m|=4$ into two parts as:

$m=+4$ and $m=-4$

Hence last choice that shows points on +4 and -4 is the correct graph.
