Answers

Step-by-step explanation:

first you have to find the value of X. So you take both expressions and make them equal to 180 degrees. Then you solve for X. Once you do that X should equal 30. Then in place of X plug in 30 and solve. it should look like this (3(30)+22). The answer is 112 degrees.

You could of also looked at your angle and saw it was an obtuse angle. The only answer that was obtuse was 112 degrees.

Step-by-step explanation:

On the left side, we have 3 people pulling with a force of 50n. That makes the total force 150. On the right side, we have 2 people pulling with 75n force which makes the total force 150n ad well. If the force is the same on each side then the rope cannot move. If they force on one of the sides was greater than the rope would move to that side

-Hope this helps

Answer:

I would say it will move to the ( Right ) because even tho there’s more students on the left there is also more force to the right making the right side have the most force.

Step-by-step explanation: so the answer is it will move to the right because of the higher force.

In the given figure QR ∥AB, RP∥ BD,CQ=x+2,QA=x,CP=5x+4,PD=3x.The value of x is

Answers

Answer:

by BPT it will be solved

Step-by-step explanation:

CQ/QA=CP/PD

x+2/x=5x+4/3x

by cross multiplication

answer will be 1

Parallel sides are sides that are equidistant from one another. The value of x is 1

Given that:

[tex]CQ = x + 2\\QA = x\\CP = 5x + 4\\PD = 3x[/tex]

Since:

QR & AB are parallel, and RP & BD are parallel.

Then by theorem of similarities:

[tex]\frac{CQ}{QA} = \frac{CP}{PD}[/tex]

This gives:

[tex]\frac{x+2}{x} = \frac{5x + 4}{3x}[/tex]

Multiply both sides by 3x

[tex]3x \times \frac{x+2}{x} = \frac{5x + 4}{3x} \times 3x[/tex]

[tex]3 \times (x+2) = 5x + 4[/tex]

Open bracket

[tex]3x+6 = 5x + 4[/tex]

Collect like terms

[tex]5x - 3x = 6 -4[/tex]

[tex]2x = 2[/tex]

Divide both sides by 2

[tex]x = 1[/tex]

Subtract b from each side to get

Mx+b=y

Step 2: Add -mx to both sides.

B=-mx +y

lol I can’t be bothered to solve for m so here’s the answer

solve for M vv

M= -b+y / x -b+y are the numerators and x is the denominator

Given kite ABCD with AD=AB, AO=3, and BD=8. Find AD.

This is to find the missing side with Vertex angles of Kite ∠A and ∠C, non-vertex angles are ∠D & ∠B, Main Diagonal bisects ∠A and ∠C and cross diagonal bisects ∠D and ∠B. Please help me find side AD

Answers

Answer:

AD = 5

Step-by-step explanation:

Given:

A kite ABCD with following dimensions:

AD = AB

AO = 3 and

BD = 8

To find:

AD = ?

Solution:

Kindly refer to the attached image for the figure of given dimensions.

In a kite, the following properties hold true:

1. The diagonals of a kite are perpendicular to each other.

2. The longer diagonal(along the vertex angles) bisects the shorter one.

Using above properties:

Looking at the [tex]\triangle AOD:[/tex]

[tex]\angle AOD=90^\circ[/tex]

AO = 3

OD = 4

We know that, Pythagoras theorem hold true in every right angled triangle.

According to Pythagorean theorem:

[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}[/tex]

[tex]AD^{2} = 4^{2} + 3^{2}\\\Rightarrow AD = \bold{5}[/tex]

The value of AD should be 5.

Calculation of the value of AD:

Since kite ABCD with AD=AB, AO=3, and BD=8

Here angle AOD = 90 degrees

And, AO = 3 and OD = 4

So, here we use the Pythagorean theorem

[tex]= \sqrt 3^2 + 4^2\\\\= \sqrt{9 + 16} \\\\ = \sqrt{25}[/tex]

= 5

Hence, The value of AD should be 5.

Is triangle ABC similar to triangle DEF? Why or why not?

Answers

Answer:

No, because not all corresponding angles are congruent.

Step-by-step explanation:

In order for two triangles to be similar you must have that you know at least 2 corresponding angles are congruent which would also imply the third set of angles are also congruent. You can also tell if two triangles are similar based on their corresponding sides being proportional. Without even checking the proportionally part of corresponding sides, I see the 3 angles in the first triangle do not have the same measurement as the one in the second triangle. Therefore, the triangles cannot possibly by similar.

Car x travels 174 miles in 3 hours

What equation describes this relation

Answers

Using the speed - distance relationship, the speed of the car is 58 miles per hour.

Recall the equation to calculate the miles per hour :

Speed = (distance ÷ time)

Distance moved = 174 miles

Time taken = 3 hours

The speed of the car in miles per hour can be calculated thus :

Speed = (174 ÷ 3) = 58 miles per hour.

Therefore, the speed of the car in miles per hour is 58 miles per hour.
