Answer:
c. 9/12
Step by step explanation.
Given: sin = 9/15
and,
[tex]sin = \frac{opp.}{hyp.} [/tex]
[tex]tan = \frac{opp.}{adj.} [/tex]
thus, find adj. side
by using Pythagoras theorem
[tex] {c }^{2} = {a}^{2} + {b}^{2} [/tex]
then,
let adj. side be a^
[tex] {a}^{2} = {c}^{2} - {b }^{2} \\ {a}^{2} = {15 }^{2} - {9}^{2} \\ {a}^{2} = 144 \\ a = 12[/tex]
thus,
adj. side is 12
then,
tan of the angle = 9/12

Marshall is comparing different companies that rent sound systems The total cost, y , for each company includes a used rental fee plus an additional fee based on the number of hours, x , the sound system is rented. Which company had the lowest additional fee per hour for renting a sound system?
Answers
Answer:
Company B
Step-by-step explanation:
Given
See attachment for graph
Required
Company with the least additional fee
This means the y-intercept and it represents the flat fee
To get the y-intercept, we simply write out the point where [tex]x= 0[/tex]
From the graph of A, we have:
[tex](x,y) = (0,70)[/tex]
Additional Charges = 70
From the table of B, we have:
[tex](x,y) = (0,50)[/tex]
Additional Charges = 50
From the equation of C, we have:
[tex]y=10x+ 90[/tex]
[tex]y(0) = 10 * 0 + 90[/tex]
[tex]y(0) =0 + 90[/tex]
[tex]y(0) =90[/tex]
Additional Charges = 90
By comparison. company B has the least additional fee because: [tex]50 < 70 < 90[/tex]

m∡ABC = 135°
Step-by-step explanation:
∡ABE ≅ ∡CBD therefore we can create the following equation:
3x + 27 = 45
3x = 18
x = 6
∡CBD and ∡ABC are supplementary so 180 - ∡CBD = m∡ABC
180 - 45 = m∡ABC
m∡ABC = 135°
Tom can paint a fence in 6 hours. Huck can paint a fence in 5 hours. If Tom takes a 30 minute break, how long will it take them to paint the fence together?
Answers
Answer:

Step-by-step explanation:
Tom can paint 1/6 of the fence in an hour
Huck can paint 1/5 of the fence in an hour
Tom takes a half-hour break; we can create this equation:
1/6x - 1/2 + 1/5x = 1

Which pair of angles has congruent values for the sin x° and the cos y°?
35°; 55°
35°; 70°
35°; 145°
35°; 35°
Answers
Answer: the correct answer is A. 35, 55
Step-by-step explanation: got it right on my exam today
35 degrees and 55 degrees are the pairs of angle have congruent value for sinx and cosx.
What is congruent angle?Congruent angles are the angles that have equal measures.
According to the given question
We have different angles for [tex]sinx[/tex] and [tex]cosy[/tex].
And we have to find "the pairs of angles which has congruent values for sinx and cosy.
Therefore,
35 degree and 55 degree
sin(35) = [tex]sin(\frac{7\pi }{36})[/tex] =0.57
cos(35) = [tex]cos(\frac{11\pi }{36})[/tex] = 0.57
⇒ 35 degrees and 55 degrees are the pair of angles has congruent values for sinx and cosy.
35 degrees and 70 degrees
sin(35) =[tex]sin(\frac{7\pi }{36} ) =0.57[/tex]
cos(70) =[tex]cos(\frac{7\pi }{18} )[/tex] = 0.34
⇒35 degrees and 70 degrees are the pair of angles have not congruent values for sinx and cosy.
35 degrees and 145 degrees.
sin(35)=[tex]sin(\frac{7\pi }{36} )= 0.57[/tex]
cos(145) = [tex]cos(\frac{29\pi }{36} )= -0.8[/tex]
⇒ 35 degrees and 145 degrees are the pair of angles have not congruent values for the sinx and cox.
35 degrees and 55 degrees
sin(35) =[tex]sin(\frac{7\pi }{36} )[/tex]= 0.57
cos(35) = [tex]\frac{x}{y} =\frac{7\pi }{36} = 0.8[/tex]
⇒ 35 degrees and 55 degrees are the pairs of angles have not congruent values for sinx and cosx.
Hence, 35 degrees and 55 degrees are the pairs of angle have congruent value for sinx and cosx.

Basically, an outlier is a point on a graph that doesn't really fit the pattern.
