Answer:
sinA = 12/13, cosA = 5/13, tanA = 12/5
sinB = 5/13, cosB = 5/13, tanB = 5/12
Step-by-step explanation:
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
Sin(A) = 12/13
Sin(B) = 5/13
Cos(A) = 5/13
Cos(B) = 12/13
Tan(A) = 12/5
Tan(B) = 5/12
Find the value of X and the value of Y.
A) x=9, y=18 square root 2
B) x=18, y=18
C) x=9 square root 2, y=18 square root 2
D) x=9 square root 3, y=18
Given:
A figure of a triangle.
To find:
The values of x and y.
Solution:
From the given triangle it is clear that the base angles of the triangle are equal, so the triangle is an isosceles triangle.
Altitude on the base of the isosceles triangle from from the opposite angle is a median. It means, it divides the base in two equal parts.
In the given triangle, the altitude divides the base in two equal parts and the measure of each part is 9 units.
In a right triangle,
[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]
[tex]\cos 60^circ=\dfrac{9}{y}[/tex]
[tex]\dfrac{1}{2}=\dfrac{9}{y}[/tex]
[tex]1\times y=9\times 2[/tex]
[tex]y=18[/tex]
And,
[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]
[tex]\tan 60^\circ=\dfrac{x}{9}[/tex]
[tex]\sqrt{3}=\dfrac{x}{9}[/tex]
[tex]9\sqrt{3}=x[/tex]
Therefore, the correct option is D.

Step-by-step explanation:
To get the total number of atoms in a compound, we should add the subscripts to get the total number.
For example:

A ball is thrown into the air with an upward velocity of 44 ft/s. It’s height h in feet after t seconds is given by the function h=-16t^2 +44t+5. How long does it take the ball to reach its maximum height? What is the balls maximum height?
9514 1404 393
Answer:
1.375 seconds35.25 feetStep-by-step explanation:
A quadratic function y=ax^2 +bx +c is symmetric about the vertical line x=-b/(2a). That is the x-coordinate of the vertex (maximum or minimum).
Here, we have ...
h = -16t^2 +44t +5
t = -44/(2(-16)) = 11/8 = 1.375
It takes 1.375 seconds for the ball to reach its maximum height.
The height at that time is ...
h = (-16(11/8) +44)(11/8) +5 = (-22 +44)(11/8) +5 = 121/4 +5 = 141/4 = 35.25
The maximum height is 35.25 feet.
Savannah has a principle of 15000 with a 4.25% and saves 1,275 in interest. How long is she saving for
Answer:
5.73 years
Step-by-step explanation:
Considering she saved 4.25% in each year of the amount $15000.
So, we have to calculate in what time her saving reaches $1275, if she save each year.
it becomes question of simple interest in which
SI = $1275, Principal P= $5000, time T, rate R = 4.25%
we know SI = PRT/100
1275 = 5000×4.25×T/100
⇒T = 1275×100/(5000×4.25)
⇒ T= 5.73 years

Mr. Armstrong went to Target to buy four pairs of dress socks. There was a 30% off sale
on the socks, and his total bill before tax was $14. What was the price of each pair of socks
before the sale?
Answer: $5
Step-by-step explanation:
We should note that since there was a 30% off sale, it means that he paid for 70% (100% - 30%) of the sales price.
Therefore, let the price of the socks be represented as x.
70% of x = 14
70/100 × x = 14
0.7 × x = 14
0.7x = 14
x = 14 / 0.7
x = 20
Therefore, the price of the socks was $20. Since there are 4 pairs, each pair will be:
= $20 / 4
= $5
A Ferris Wheel has a radius of 16 feet. How far will you travel if you take a ride that goes around 5 times? Round answer to the nearest hundredth and for pi use π = 22 7 .
Answer:
502.85 feet
Step-by-step explanation:
Given that,
The radius of a Ferris wheel, r = 16 feet
We need to find how far will you travel if you take a ride that goes around 5 times.
Distance = 5×2πr
So,
= 10πr
[tex]=10\times \dfrac{22}{7}\times 16\\\\=502.85\ \text{feet}[/tex]
So, the required distance is 502.85 feet.

Answer:
y=36degrees
Step-by-step explanation:
74+2y+34=180
2y+108=180
2y+108-108=180-108
2y=72
72/2
y=36degrees
Answer:
Step-by-step explanation:
Because these are supplementary angles they must have a sum of 180 degrees.
74+2y+34=180
2y+108=180
2y=72
y=36 degrees
Is AQRS a right triangle? Why or why not?
A. No, AQRS is not a right triangle, because QS would have to be 2.23.
B. Yes, AQRS is a right triangle by the Pythagorean theorem.
C. No, AQRS is not a right triangle, because QS would have to be./89.
D. No, AQRS is not a right triangle, because QS would have to be 83.
Answer:
D i searched it up and thats what the answer is
Answer:
C. is the right answer.
Step-by-step explanation:
by using pythagoras theorem which is:
C^2=a^2+b^2
the square root of 5 is 25
and the square root of 8 is 64
C^2=25+64
C^2=89
now get rid of the square
C=the square root of 89
Find the value of x and y! Also their given relationship. Ty!
Answer:
x = 3, y = 30.4
Step-by-step explanation:
From the given diagram;
8x - 3 = 6x+3 (alternate exterior angle are equal)
Collect like terms
8x - 6x = 3 + 3
2x = 6
x = 6/2
x = 3
Also;
8x - 31 + 5y + 35 = 180 (sum of angle on a straight line is 180)
8(3) - 31 + 5y + 35 = 180
5y + 24 - 31 + 35 = 180
5y + 28 = 180
5Y = 180 - 28
5Y = 152
y = 152/5
y = 30.4
Hence x = 3, y = 30.4
