In triangle xyz what is the cosine ratio of angle x
Jobisdone [24]
<span>Data:
</span><span>Hypotenuse is 7.5 
Opposite of angle x is 6</span><span>

Cosine = Side opposite (S.O) the angle on the hypotenuse (h)

We have:

</span>Cos (\alpha)x =  \frac{S.O}{h}
Cos (\alpha)x = \frac{6}{7.5}
\boxed{Cos (\alpha)x = 0.8}

Which equation shows the same relationship as 72 x 1/8 = 9?
Nadusha1986 [10]

Hey there!

72 * 1/8 = 9

= 72/1 * 1/8

= 72(1) / 1(8)

= 72 / 8

= 72 ÷ 8

= 9


Thus, the answer could either be:

• 72/1 * 1/8

• 72 / 8

OR

• 72(1) / 1(8) (hence how we possibly received answer number 2)


Good luck on your assignment & enjoy your day!

tudents are given 3 minutes for each multiple-choice question and 5 minutes for each free-response question on a test. There are
AlladinOne [14]
In this question, they gave you the system of equations. You just need to use the two of them.

We want to find the m or the number of the multiple-choice questions. So we need to turn our last equation in the form of 'm's by translating the 'f's into 'm's.

m + f = 15
f = 15 - m

If we know the m form of f, we can convert the second equation and find the answer: 3m + 5f = 51

Plug in the m value of f: 3m + 5(15 - m) = 51

Distribute the 5: 3m + 75 - 5m = 51

Subtract -75 from both sides: 3m - 5m= 51 - 75

Combine like terms: - 2m = - 24

Divide both sides by -2: m = 12

So, we learned that the number of the multiple-choice questions is 12.

Suppose you have to use right-triangle trigonometry to find the apothem of a regular polygon. Which is greater, the apothem or t
asambeis [7]
The apothem represents one side of the right triangle to be solved. Specifically, it represents the height of the triangle.
 The radius of the polygon represents the hypotenuse of the right triangle that is going to be solved.
 Therefore, we can infer that the radius of the polygon is greater than the apothem because the hypotenuse is greater than all sides of a triangle.
 Answer:
 the radius of the polygon is greater
