Solve Using Trigonometry, Find Missing Side

Answers

Answer 1

Answer:

Step-by-step explanation:

1. sin 30 = x/16

   x= 16 sin 30

   x = 8

2. cos 60 = 22/x

   x = 22/cos 60

   x = 44

3. tan 45 = x/19

  x = 19 tan 45

   x= 19

4. tan 16 = x/13

   x = 13 tan 16

   x= 3.73

5. sin 54 = x/45

  x = 45 sin 54

  x= 36.41

6. sin 35 = z/23

 z =   23 sin 35

  z = 13.19

Find the length of midsegment JN in the trapezoid.

Answers

Answer:

JN = 18.6

Step-by-step explanation:

Theorem:  The length of the midsegment of a trapezoid is the average of the bases.

[tex]JN = \frac{15.4 + 21.8}{2}[/tex]

       [tex]= \frac{37.2}{2}[/tex]

       = 18.6

See how easy that is when you know the theorem.

determine the missing side lengths​

Answers

Answer:

Given that is a 45-45 triangle, the hypotenuse should be x[tex]\sqrt{2}[/tex], so in this case. The hypotenuse should be 3[tex]\sqrt{2}[/tex], and the other side lengths 3. I see no other way of it going other than that one; I hope I helped at least a bit!

Step-by-step explanation:

Answer:

base =3in and hypotenuse =3√2

Step-by-step explanation:

relationship between perpendicular and hypotenuse is given by sin angle

sin 45=p/h

sin45=3in/h

h=3in/sin45=3√2 inch

relationship between perpendicular and base is given by tan angle

tan45=P/b

b=3in/tan45=3in

Answer How many solutions does the nonlinear system of equations graphed below have?

Look at the number of points where the graphs intersect each other...the points where the graphs of the functions cross each other are the solutions to the system.

Upon looking, you should see 4 points where the graphs intersect, so there are 4 solutions to the non-linear system of equations.

Answer:

y=-2/5x+2

Step-by-step explanation:

use y = mx + b

m = slope = rise/run = 2/5

b = y-intercept when x is zero (0,y) = (0,2) = 2

since the line is going down, the slope has to be negative.

answer: y = -2/5(x) + 2

Find the circumference and area of a circle to the nearest hundredth. Use 3.14 for pie. Round to the nearest hundredth if necessary. The diameter is 52.

Answers

Answer:

Circumference = 163.28 unitsArea = 2,122.64 units²

Step-by-step explanation:

Circumference

Circumference of a circle is calculated by the formula:

= π * diameter

= 3.14 * 52

= 163.28 units

Area

Area of a circle is calculated by the formula:

= π * radius²

Radius = DIameter / 2

= 52 / 2

= 26 units

Area = 3.14 * 26 * 26

= 2,122.64‬ units²

5, find A'B'.

Answers

Answer:

72in

Step-by-step explanation:

If AB = 24 inches and AB is dilated by a scale factor of 3, then A'B' is gotten by multiplying the AB by the sclae factor as shown;

A'B' = 3AB

A'B' = 3(24)

A'B' = 72 in

Hence the length of A'B' is 72in

Answer:

Given function:

g(x) = x² - 6x + c

a)

c = 2

Th x-intercept found when g(x) = 0

x² - 6x + 2 = 0

Solve the equation to find the values of x:

x² - 6x + 2 = 0x² - 6x + 9 = 7(x - 3)² = 7x - 3 = ±√7x = 3 ± √7

The x-intercepts are (3 + √7, 0) and (3 - √7, 0)

b)

c = 10

Solve as above:

x² - 6x + 10 = 0x² - 6x + 9 + 1 = 0(x - 3)² = -1

The left side is a square of a number which is always positive, the right side is negative.

It means there is no solution, so no-x-intercepts.

The graph of the function lies above the x-axis.
