it is contrapositivei could not see the question too well so check yourself again too . this is because i want you to get it correct.Reply
The trigonometry ratio that we shall use to solve the question will be:tan θ=opposite/adjacentwhere:opposite=8.9 cmadjacent =x cmθ=55°plugging the values and simplifying we obtain:tan 55=8.9/xthusx=8.9/tan55x=6.23 cm~6.2 cm AReply
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 18cos x° = adjacent side/hypotenuse = 16/18 = 8/9x° = cos inverse(8/9) = 27.12° = 30° (Rounded off to nearest ten)Reply

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

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

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
