find value of x. ROUND TO NEAREST HUNDREDTH. PLS HELP. WILL AWARD BRAINLIEST
Answers
Answer:
[tex]x[/tex] = 24.57 to the nearest hundredth
Step-by-step explanation:
The three sides of a right-angled triangle have specific names:
The hypotenuse (H) is the longest side. It is opposite the right angle.The opposite side (O) is opposite the angle in question.The adjacent side (A) is next to the angle in question.The 3 trigonometric ratios are:
[tex]sin(\theta)=\frac{O}{H} \\\\cos(\theta)=\frac{A}{H} \\\\tan(\theta)=\frac{O}{A}[/tex]
For the given triangle we are given the angle, the hypotenuse, and need to find the side that is ADJACENT to the angle.
Therefore, we would use the trig ratio: [tex]cos(\theta)=\frac{A}{H}[/tex]
Substituting the values from the triangle: [tex]cos(35)=\frac{x}{30}[/tex]
Multiply both sides by 30: [tex]30cos(35)=x[/tex]
Therefore, [tex]x=24.57456133...[/tex]
So [tex]x[/tex] = 24.57 to the nearest hundredth

====================================================
Explanation:
Use the cosine ratio to get the following,
cos(angle) = adjacent/hypotenuse
cos(71) = 20/x
x*cos(71) = 20
x = 20/cos(71)
x = 61.431 approximately
x = 61.4
Notes:
The hypotenuse is always the longest side of any right triangle, so x must be larger than 20.Make sure your calculator is in degree mode.Answer:
x ≈ 61.4
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos71° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{20}{x}[/tex] ( multiply both sides by x )
x × cos71° = 20 ( divide both sides by cos71° )
x = [tex]\frac{20}{cos71}[/tex] ≈ 61.4 ( to the nearest tenth )

B) Write a multiplication number sentence to check your answer:
C) Show how many tables Avery paints:
Answers
Answer:
please see analysis
Step-by-step explanation:
You can do this with a proportion. It takes 5/6 of a gallon to paint 1 wall and you want to know how much of a wall can you paint with 1/2 gallon. So set up the proportion:
5/6 / 1 = 1/2 / x
cross multiplying gets you 5/6x = 1/2
multiply by the reciprocal of 5/6 to isolate x - which is 6/5. 1/2 times 6/5 = 3/5

but the equation was 6x + 50 = 92
In order to find x, you have to isolate it from the rest of the equation
Subtract 50 from both sides to get:

Vijay's family is leaving for Galactic Gardens Resort once his parents get home from work on Friday. Their house is 544 miles from the resort. They plan to stop and spend the night at a hotel after 3 hours of driving, then complete the rest of the trip on the second day. If their average speed is 64 miles per hour, how long will they drive on the second day?
Answer is not multiple choice!
Write your answer as a whole number or a decimal.
Answers
Answer:
5.5 hours i think
Step-by-step explanation:
64 x 3 = 192 for the first day
544 - 192 = 352
64 x 5.5 = 352
therefor your anwser is 5.5
The time taken by Vijay's family to drive on the second day is 5.5 hours.
What is speed?Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.
The time is calculated as:-
For 3 hours of driving at an average speed of 64 miles per hour, the distance covered is,
d = 64 x 3 = 192miles
Miles remaining for the second day is,
544 - 192 = 352 miles
Time taken to cover 352 miles second day is,
T = 352 / 64 = 5.5 hours

X=5
Answer:
x = 127
Step-by-step explanation:
[tex]7-\sqrt[3]{2-x} = 12[/tex] , add the cube root to both sides and subtract the 12
[tex]7-12 = \sqrt[3]{2-x}[/tex], combine like terms
[tex]-5 = \sqrt[3]{2-x}[/tex], raise both sides to the third power
[tex](-5)^{3} = (\sqrt[3]{2-x} )^{3}[/tex], simplify
[tex]-125= 2-x[/tex] , to isolate the variable subtract 2 from both sides
[tex]-125-2 =-x[/tex], combine like terms
[tex]-127=-x[/tex], multiply both sides by -1

Answers
Answer:
x=20
Step-by-step explanation:
To find x use the fact that all triangle's angles sum to 180. This means that if you add all of the angles together, they will always equal 180 degrees. So, create an equation to represent this.
The equation looks like this:2x+65+75=180
Then, combine the like terms2x+140=180
Next, subtract 140 from both sides2x=40
Finally, divide both sides by 2x=20
This means that the missing angle is 40 degrees.
