How to find the length of AB

Mathematics
2 answers:
Andrej [43]3 years ago
6 0

Answer:

The answer is option C

Step-by-step explanation:

To find the length of AB we use sine

sin∅ = opposite / hypotenuse

From the question

The hypotenuse is AB

The opposite is AC

So we have

sin 54 = AC/AB

sin 54 = 16 / AB

AB = 16/sin 54

AB = 19.777

<h3>AB = 19.78</h3>

Hope this helps you

Answer:

AB = 19.78

Step-by-step explanation:

From the diagram (Right-angle triangle):

AC = 16

AB = ?

Angle = 54°

Applying trig ratio:

Tan 54° = 16/BC

1.376381920 = 16/BC

Therefore;

BC = 16/1.376381920

BC = 11.62

To solve the length AB:

Cos 54° = BC/AB

0.587785252 = 11.62/AB

Solving AB gives:

AB = 11.62/0.587785252

AB = 19.78

2) What is the inequality that this graph represents? -15 # 3 6 x​
kvasek [131]

Answer:  y < -\frac{1}{2}x+3

This is the same as writing y < (-1/2)x+3

==============================================================

Explanation:

The dashed boundary line goes through (0,3) and (4,1)

Apply the slope formula for those two points

m = (y2-y1)/(x2-x1)

m = (1-3)/(4-0)

m = -2/4

m = -1/2

The slope of the dashed line is -1/2. The y intercept is 3. So we go from y = mx+b to y = (-1/2)x+3 to represent the equation of the dashed line. This is the same as writing y = -\frac{1}{2}x+3

We shade below the dashed line to represent the inequality y < -\frac{1}{2}x+3. Points in the shaded region are solutions to the inequality. One example point is (0,0).

Note that we don't have "or equal to" as part of the inequality sign because we are not including points on the boundary. A solid line, rather than a dashed line, would include points on the boundary.

Can anyone help I have tried finish for days
devlian [24]

Answer:

34 degrees.

Step-by-step explanation:

First of all, the sum of a triangle's degree is 180.

The angle next to the 101 is 79 degree due to the rule of supplementary angle. The angle vertical to 28 is also 28. (Vertical angles are equal).

Now we now the two side, we can figure out the last side.

180-28-79= 73

The last angle is 73 degrees. However, we are looking for x.

x+39=73

All we have to do now is subtract 39 from 73, and that leaves us with 34.

These two area models represent 2323 and 6969. Choose the equation that shows why 2323 and 6969 are equivalent.
grandymaker [24]
Well lets lay it out


     2323      6969
 
     first get 2323 and try its multiples.

     2323 x 2 = 4646
     2323 x 3 = 6969
  
   so what 2323 and 6969 have in common are the multiple 3

Answer: they are equivalent because they can be divided into each other. HOPE I  HELPED!! :P <span />
