Find the measure of angle X in the triangle below.

daser333 [38]

Use the Law of Sines to solve.

24/Sin 67.38 = 26/Sin X
Cross multiply
26Sin 67.38 = 24SinX
Divide both sides by 24
(26Sin67.38)/24 = Sin X
Use Sin^-1 to find the angle measure.
Sin^-1 [(26Sin67.38)/24]
x = 89.92 degrees

Evaluate 3/7r + 5/8s when r= 14 and s= 8

jasenka [17]

Answer:

Step-by-step explanation:

Step 1:

3/7r+5/8s

Step 2:

So u multiply 3/7 by 14

3/7 x 14= 42/7= 6

Step 2.5:

Now u multiply 5/8 by 8

5/8 x 8= 40/8= 5

Step 3:

6+5=11

6. Which of the following is the graph of the equation y = −2x2 − 3x + 4?

Stells [14]

Answer:

From the looks of the graph, it looks like the answer will be Letter C. (The last graph).

Step-by-step explanation:

Graph the parabola using the direction, vertex, focus, and axis of symmetry.

Direction: Opens Down

Vertex: ( − 3 /4 , 41 /8 )

Focus: ( − 3 /4 , 5 )

Axis of Symmetry: x = − 3 /4

Directrix: y = 21 /4

A ladder is leaning against a

vlada-n [284]

Answer:

The angle of elevation is 36.87 degrees

Step-by-step explanation:

see the attached figure to better understand the problem

In the right triangle ABC of the figure

$cos(\theta)=\frac{AC}{BC}$ ----> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

$cos(\theta)=\frac{12}{15}$

$\theta=cos^{-1}(\frac{12}{15})=36.87^o$
