Answer 2

The value of Sin 45° is 1/√2

What are trigonometric functions?

In mathematics, trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent.

Given here Sin 45° and Sin 45 degrees is the value of sine trigonometric function for an angle equal to 45 degrees. The value of sin 45° is 1/√2 or 0.7071 (approx).

Hence, the value of Sin 45° is 1/√2

Suppose that Sin(θ)=5/13 and cos(θ)=-12/13. Find the value of tan(θ), cot (θ), CSC (θ), and sec (θ). Find the value of tan(2θ)
I know the values are tanθ=5/12, cscθ=13/5, secθ=13/-12 and cotθ=-12/5 but I don't know how to find tan(2θ)

Answers

Answer:

Because θ lies in quadrant II, 2θ must lie in quadrant IV. This means the tangent of 2θ is negative.

The adjacent side to θ is 7 because √(25²-24²)=7, so tanθ=7/24.

The double angle formula for tangent is tan 2θ = (2 tan θ) / (1 − tan² θ).

Substituting the value for tanθ in and keeping in mind that this is in quadrant IV, we get tan 2θ = -(2(7/24)/(1-(7/24)²)).  

Simplified, this becomes tan 2θ = -336/527.  

Therefore, the answer is C. -336/527.

Let |u| = 10 at an angle of 45° and |v| = 13 at an angle of 150°, and w = u + v. What is the magnitude and direction angle of w?

a) |w| = 9.4; θ = 72.9°
b) |w| = 9.4; θ = 107.1°
c) |w| = 14.2; θ = 72.9°
d) |w| = 14.2; θ = 107.1°

Answers

Answer:

D

Step-by-step explanation:

Here, the direction angle is 107.1° and the magnitude is 14.2. Therefore, option D is the correct answer.

Given that, |u| = 10 at an angle of 45° and |v| = 13 at an angle of 150°.

We need to find magnitude and direction angle of w.

We have, w = u + v, θ=45° and ϕ=150°.

[tex]u_{x}[/tex]=|u|cosθ=10cos45°=7.071

[tex]u_{y}[/tex]=|u|sinϕ=[tex]u_{y}[/tex]=|10sin45°=7.071

[tex]v_{x}[/tex]=|v|cosθ=13cos150°=-11.25833

[tex]v_{y}[/tex]=|v|sinϕ=[tex]v_{y}[/tex]=13sin150°=6.5

Using this information, we get

[tex]R_{x} =u_{x} +v_{x}[/tex]=7.071-11.25833=-4.18733

[tex]R_{y} =u_{y} +v_{y}[/tex]=7.071+6.5=13.571

Direction angle=[tex]tan^{-1}[/tex](Ry/Rx)

Direction angle=[tex]tan^{-1}[/tex](13.571/-4.18733)

=-72.8239 or 107.1476≈107.1

Now, [tex]|w|=\sqrt{(|u|cos \theta +|v|cos \phi )^{2}+(|u|sin \theta +|v|sin \phi )^{2}}[/tex]

=[tex]|w|=\sqrt{(10cos45\textdegree +13cos150\textdegree )^{2}+(10sin 45\textdegree+13sin150\textdegree)^{2}}=14.2026[/tex]

Here, the direction angle is 107.1° and the magnitude is 14.2. Therefore, option D is the correct answer.

The supplement of measure of 164 degree angle is 16 degrees.
The bigger triangle is a right triangle, meaning it has an angle of 90 degrees.

We can find the big angle on the top by adding both angles we know of together and subtract that from 180 degrees because all interior angles of a triangle add up to 180 degrees:
180 - (90 + 16) = 180 - 106 = 72 degrees

According to the picture, the angle appears to be bisected, meaning it has been divided into two congruent angles.
Take the 72 degree angle and divide it by 2 to get the measure of each angle. Each angle is 36 degrees.

Finally, add the measures of the 36 degree and 16 degree angle and subtract that from 180 degrees to get the measure of the unknown angle (the value of x).
180 - (36 + 16) = 180 - 52 = 128 degrees

x = 128 degrees

I think this is the answer.

The sum of the digits of certain two-digit number is 9. Reversing its digits increase the number by 45. Find the number.
A) 36
B) 30
C) 27
D) 26

Answers

the answer would be A

If the original number can be written as ab, where a is the digits in the tens place and b is in the ones place, then it can be expanded as

10a + b

where a and b are chosen from {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}. The sum of the digits is 9, so

a + b = 9

Reversing the digits gives the number ba, or

10b + a

which is larger than ab by 45, so

10b + a = (10a + b) + 45

-9a + 9b = 45

a - b = -5

Solve for a and b :

(a + b) + (a - b) = 9 + (-5)

2a = 4

a = 2

Then

a + b = 9

2 + b = 9

b = 7

So the original number if (C) 27.
