In PQR, Q= 76, PQ = 18, And QR = 27 Please Find Angle P, T And PR For 5

Answers

Answer 1

Answer:

Step-by-step explanation:

Given:

m<Q = 76°

PQ = r = 18

QR = p = 27

Required:

Find P, T, and PR (q)

Solution:

✔️To find PR(q), apply the Law of Cosines.

Thus:

q² = r² + p² - 2rp×cos(Q)

Plug in the values

q² = 18² + 27² - 2×18×27×cos(76)

q² = 1,053 - 235.148

q² = 817.852

q = √817.852

q = 28.6 (nearest tenth)

✔️Find P by applying the Law of Sines:

[tex] \frac{sin(P)}{p} = \frac{sin(Q)}{q} [/tex]

Plug in the values

[tex] \frac{sin(P)}{27} = \frac{sin(76)}{28.6} [/tex]

[tex] sin(P) = \frac{sin(76)*27}{28.6} [/tex]

[tex] sin(P) = 0.9160 [/tex]

[tex] P = sin^{-1}(0.9160) [/tex]

P = 66.3° (nearest tenth)

✔️R = 180 - (P + Q)

R = 180 - (66.3 + 76)

R = 37.7°

How can you tell that (448 + 217 + 34) × 9 is three times as large as (448 + 217 + 34) × 3 without doing complicated calculations?

Answers

I can tell that (448+217+34) x9 is 3 times larger than (448+217+34) x3 because the number inside the equations are being multiplied by 9 which is 3 times bigger than 3 ( the number being multiplied in the 2nd one)(3x3)

Answers

Answer:

[tex]a_{n} = 11 - 5n[/tex]

Step-by-step explanation:

use the formula

[tex]a_{n} = a_{1} + (n - 1)d[/tex]

-14 = 6 + (5 - 1)d

-14 = 6 + 4d

-20 = 4d

d = -5

[tex]a_{n} = 6 + (n - 1)(-5) = 6 - 5n + 5 = 11 - 5n[/tex]

What are the six trigonometric ratios?

Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.

In a right-angled triangle, two such angles are there which are not right angled(not of 90 degrees).

The slanted side is called the hypotenuse.

From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.

The given function is f(x)= asin(b(x-h)) where we have to find the value of a , b and h.

f(x)= sin 2x – 3 cos 2x

If we substitute the value of a, b and h then we get the same solution for both the equation.

a = 3.16

b = 2

h = 0.62

Thus, option B is the correct match for the values.

find the surface area of the cube below.

Answers

Answer:

150

Step-by-step explanation:

surface area =6a^2

= 6(5^2)

= 6×25

=150

Answer:

150 cm²

Step-by-step explanation:

So, firstly we must understand what does total surface area means (T.S.A)

We intuitively know that, it means,

Area of 6 EQUAL faces.

So,

Edge of the cube = 5 cm

Area of 1 face= 5 × 5= 25 cm²

Area of 6 faces= 25 × 6= 150 cm².

So, that means,

T.S.A= 150 Cm²

Answers

Answer:

≈ 12.6

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the third side, then

x² + 6² = 14²

x² + 36 = 196 ( subtract 36 from both sides )

x² = 160 ( take the square root of both sides )

x = [tex]\sqrt{160}[/tex] ≈ 12.6 ( to the nearest tenth )

So, let the diameter of this circle be x.

Which means :

[tex] =\tt2 \times \pi \times r[/tex]

[tex] =\tt 2 \times x \times \pi = 12\pi[/tex]

[tex] =\tt 2x\pi = 12\pi[/tex]

Thus, the radius of the circle Robert drew = 6 m

Since the circle in option B has a radius of 6 m, it is the circle Robert drew.

Mary bought 5 pairs of gloves and 2 hats for $95. Mary received a text from her friend Joanna ask her to buy 4 pairs of gloves and a hat. Mary told Joanna that the cost was $70. How much does each pair of gloves cost? How much does the hat cost?

Answers

Answer: Each pair of gloves costs $15 and each pair of hat costs $10.

Step-by-step explanation:

Let x = Cost per pair of gloves

y= Cost per hat.

As per given, we have

[tex]5x+2y=95 \ \ \ \ (i)\\4x+y=70\ \ \ \ \ (ii)[/tex]

Multiply (ii) by 2 , we get

[tex]8x+2y=140\ \ \ \ (iv)[/tex]

Eliminate (i) from (iv), we get

[tex]3x=45\\x=15[/tex]

Put this in (ii), we get

[tex]4(15)+y=70\\60+y=70\\y=10[/tex]

Hence, each pair of gloves costs $15 and each pair of hat costs $10.
