Answer:

130.5

Step-by-step explanation:

The solution is,  the value of x is approximately 116.5 meters.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

here, we have,

We are given the following information

From this picture, we want to find the vaule of x. To so, we will use the sine law. to solve this problem.

The sine law relates the sine of the angles of the triangle and the length of the opposite sides of the triangle. If we have a triangle of the form

Then,the sine law states that

sinA/a =sinB/b =sinC/c

Which is equivalent to

a/sinA = b/sinB = c/sinC

In our case, we are given the measure of angles A and B and missing the measure of angle C. Also, we are given the measure of side c. If we apply the sine law to the given triangle we have

x/ sin 35  = 200/ sin 80

So, first we need to identify the value of C. To do so, we will use the following fact:

The sum of the inner angles of a triangle is 180°.

Then, we have the following equation

65 +35 +C = 180

If we operate on the left side, we get

100+C = 180

So, by subtracting 100 from both sides, we get

C= 80

So, if we replace the value of C in the equation we had, we get

x/ sin 35  = 200/ sin 80

If we multiply both sides by sin(35) we get

x = 200* sin 35/ sin80

so, using a calculator we get

x = 116.5

so the value of x is approximately 116.5 meters

Answer:

4 times larger

Step-by-step explanation:

3² = 9

(3+3)² = 36

36 is four times larger than 9

Step-by-step explanation:

angle B+angle C = 180°

= angle B= 180-79

= angle B = 101°

therefore angle A = 79°

angle D = 101°

this sequence is decreased by 3 for every digit

Answers:

x = 6 and P = 128

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

Explanation:

The tangents CT and CU are equal to each other. The rule is that tangent segments that meet at a common point are the same length.

Let's solve for x

CT = CU

3x = 18

x = 18/3

x = 6

Because CT = 18, this makes BC = BT+TC = 12+18 = 30

---------------------------

For similar reasoning as mentioned earlier, we can say tangents BT and BV are the same length. This means BV = 12.

Segment CD = 52 and CU = 18, which makes UD = CD-CU = 52-18 = 34

From there, we can say segment DV = 34 also. This leads to BD = BV+VD = 12+34 = 46

Triangle BCD has the three sides

The perimeter is

P = sum of the three sides

P = (side1)+(side2)+(side3)

P = BC + CD + BD

P = 30+52+46

P = 82+46

P = 128

Answer:

(-2, -3)

Step-by-step explanation:

y=2x + 1

y= 0.5x - 2

2x+1= 0.5x -2

1.5x= -3

x= -2

y= 2x+ 1

y= 2(-2)+1

y= -3

The solution is (-2,-3)

The solution to the set of simultaneous equations is; (-2, -3)

We are given the equations;

y = 2x + 1   ---(eq 1)

y = 0.5x - 2   ---(eq 2)

subtract eq 2 from eq 1 to get;

0 = 2x - 0.5x + 1 - (-2)

0 = 1.5x + 3

x = -3/1.5

x = -2

Thus;

y = 2(-2) + 1

y = -4 + 1

y = -3

Step-by-step explanation:

Let xy = k, where k is the constant of variation.

By using values of x and y in the table,

we see that (2)(48) = (4)(24) = (12)(8) = 96.

Hence k = 96, which is our answer.

Answer:

d = 7

Step-by-step explanation:

In the circle shown, the radius is 3.5. The diameter is double the radius (d = 2r), so:

d = 2 (3.5)

d = 3.5 + 3.5

d = 7

Answer:

Step-by-step explanation

f(x) and g(x) are inverse functions.  Note that the logrithmic notation for [tex]f(x) = y = b^{x} \\ is\\ log y_{b} = x[/tex]

So, when x = 1.477,  f(x) = y = 30

and when x = 20, g(x) = y = 1.301

Answer:

r = 1

Step-by-step explanation:

slope = change in y / change in x, so:

change in y / change in x  = 2/3

5 - r / 7 - 1 = 2/3

5 - r / 6 = 2/3

[tex]\frac{5-r}{6}=\frac{2}{3}[/tex]

now solve this equation.

first, multiply both sides by 6 to get rid of the fraction:

[tex]5 - r = 4[/tex]

subtract 5 from both sides

[tex]-r=-1[/tex]

multiply both sides by -1

[tex]r=1[/tex]
