Answer:

the measure of angle P is 61.93°

The value of angle P of the triangle ΔPQR is ∠P = 61.93°

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the triangle be ΔPQR

Let the angle ∠P = θ

Triangle ΔPQR  is a right angle triangle

where ∠Q = 90°

Now , the value of the sides are

PQ = 8 cm

QR = 15 cm

PR = 17 cm

Now , from the trigonometric relations

∠QPR = θ

tan θ = opposite side / adjacent side

Opposite side of Triangle PQR is QR

Adjacent side of Triangle PQR is PQ

So , substituting the values in the equation , we get

tan θ = opposite side / adjacent side

tan θ = QR / PQ

tan θ = 15 / 8

tan θ = 1.875

Now , the value of θ is

The value of θ = tan⁻¹ ( 1.875 )

The value of θ = 61.93°

Therefore , the value of θ is 61.93°

Hence , The value of angle P of the triangle ΔPQR is ∠P = 61.93°

Answer:

  a) NT = 8

  b) RS = 8

  c) RT = 16

  d) ZR = 24

Step-by-step explanation:

All of the marked sides are congruent. (That's what the marks mean.) It might help you to put 8 next to each hash mark like it is on NS. So, you have ...

  NT = RS = ST = TZ = NS = 8

Segments on the same line sum, so ...

  RT = RS +ST = 2RS = 16

  ZR = RS +ST +TZ = 3RS = 24

a) NT = 8

b) RS = 8

c) RT = 16

d) ZR = 24

Find miles per hour by dividing total miles by total time:

240 miles / 3 hours = 80 miles per hour.

Now multiply miles per hour by time:

80 miles per hour x 2 hours = 160 miles.

Answer: n = 152 m

Step-by-step explanation:

write a proportion to find n.

46/n = 92/204

n = 102 m

The length of the lake shown in the provided image using similar triangles and a proportion is 102 meters.

In the two similar triangle, the ratio of two sides of one triangle is equal to the ratio of corresponding sides of the other triangle.

In the figure shown,

The total length of the base of the larger triangle is,

[tex]112+92=204\rm\; m[/tex]

The height of this triangle is n meters, which is equal to the length of lack. Thus, by the similar triangle proportion property,

[tex]\dfrac{n}{204}=\dfrac{46}{92}\\n=\dfrac{46\times204}{92}\\n=120\rm\; meters[/tex]

Thus, the length of the lake shown in the provided image using similar triangles and a proportion is 102 meters.

Answer:

  g(x) = 3x^2 -2

Step-by-step explanation:

Reflection in the y-axis replaces x with -x.

  g(x) = f(-x) = 3(-x)^2 -2

  g(x) = 3x^2 -2

_____

The given function is symmetrical about the y-axis, so its reflection is itself.

Answer: Choice A.

Knowing that 5^2 + 12^2 = 13^2, draw the 5 cm side and the 12 cm side with a right angle between them. The 13 cm side will fit to form a right triangle.

The diagram is shown below.

The converse of the pythagorean theorem states that if a^2+b^2 = c^2, then we have a right triangle with hypotenuse c. The hypotenuse is always the longest side and always opposite the 90 degree angle.

Note how 5^2+12^2 = 25+144 = 169 while 13^2 = 169, so that shows how 5^2+12^2 = 13^2 is true.

Answer:

x = 18

Step-by-step explanation:

5x/9 = x/6 + 7

multiply both sides by 9

5x = 9x/6 + 63

multiply both sides by 6

30x = 9x + 378

subtract 9x from each side

21x = 378

divide both sides by 21

x = 18

check by substituting 18 for x:

5(18)/9 = 18/6 + 7

5(2) = 3 + 7

Answer:

Center = (5,-3) and radius = 7

Step-by-step explanation:

(5) If Oskar bisects the diameter of a circle, what is he trying to construct the radius of the circle.

(6) The given equation is :

[tex](x-5)^2+(y+3)^2=49[/tex]

The general equation of circle is given by :

[tex](x-a)^2+(y-b)^2=r^2[/tex] ...(1)

Where

(a,b) are the coordinates of the centre and r is the radius.

The given equation can be written as :

[tex](x-5)^2+(y+3)^2=7^2[/tex] ..(2)

Comparing equation (1) and (2) we get :

a = 5, b = -3 and r = 7

So,

Center = (5,-3) and radius = 7

Hence, this is the required solution.

Answer:

y = 10 and x =18

Step-by-step explanation:

From the parallelogram,

DH + HF = DF

x+2 + 2y = DF

Also DH = HF

x+2 = 2y

x - 2y = -2 .... 1

Also GH = HE

3x-3 = 5y+1

3x - 5y = 1 + 3

3x-5y = 4 .... 2

Solve  1 and 2 simultaneously

x - 2y = -2 .... 1 * 3

3x-5y = 4 .... 2 * 1

_____________

3x-6y = -6

3x-5y = 4

Subtract

-6y + 5y = -6-4

-y = -10

y = 10

Substitute y = 10 into 1

x- 2y = -2

x - 2(10) = -2

x - 20 = -2

x = -2+20

x = 18

Hence y = 10 and x =18
