27.3 degrees

cos x = 16/18

x = arccos(16/18)

x = 27.3 degrees

The correct answer is 8.36

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.

Given that:

(x+2)(2x-5)=54

We have:

[tex]2x^2-x-64=0[/tex]

Using the quadratic formula, this is approximately 5.66, so rounded to the nearest whole number, our answer is 6.

Here the angle is given as 55°

With respect to 55°,

8.9 cm is the opposite side

x cm is the adjacent side.

The trigonometric ratio associating these sides is tan

[tex]tan\theta=\frac{Opposite}{Adjacent}[/tex]

Substituting the values we get

[tex]\frac{8.9}{x}=tan55^{o}[/tex]

Multiplying both sides by x we get

[tex]8.9=xtan55^{o}[/tex]

Dividing by tan55° on both sides

[tex]\frac{8.9}{tan55^{o} } =x[/tex]

So we get

[tex]x=6.2[/tex] cm

Option a) is the right answer.

answer:

the answer was 75.2 ) i think if im wrong im really sorry

step-by-step explanation:

Given that:

(x+2)(2x-5)=54

We have:

[tex]2x^2-x-64=0[/tex]

Using the quadratic formula, this is approximately 5.66, so rounded to the nearest whole number, our answer is 6.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

The trigonometry ratio that we shall use to solve the question will be:

tan θ=opposite/adjacent

where:

opposite=8.9 cm

adjacent =x cm

θ=55°

plugging the values and simplifying we obtain:

tan 55=8.9/x

thus

x=8.9/tan55

x=6.23 cm~6.2 cm

A

Value of x is 30°

Step-by-step explanation:

Step 1: Find value of x by using the trigonometric ratio cosine of x. Here, given that adjacent side is 16 and hypotenuse is 18

cos x° = adjacent side/hypotenuse = 16/18 = 8/9

x° = cos inverse(8/9) = 27.12° = 30° (Rounded off to nearest ten)

10^0.63 = x

x=4.27 to the nearest hundredth

hope this helps
