What are the angle measures of triangle VUW?

m∠V = 30°, m∠U = 60°, m∠W = 90°
m∠V = 90°, m∠U = 60°, m∠W = 30°
m∠V = 30°, m∠U = 90°, m∠W = 60°
m∠V = 60°, m∠U = 90°, m∠W = 30°

Answers

Answer:

m∠V = 60°, m∠U = 90°, m∠W = 30°

Step-by-step explanation:

hope this helps y'all out

The angle measures of triangle VUW are m∠V = 90°, m∠U = 60°, m∠W = 30°

Application of SOH CAH TOA identity

From the given diagram;

Opposite side to <V = 3√3 cmHypotenuse = 6cm

According to the rule:

sin <V = opp/hyp

sin <V = 3√3/6

sin <V = √3/2

<V = 60 degrees

Since the triangle is right-angled, the measure of m<U is 90 degrees

Also, the sum of interior angle of a triangle is 180 degrees, hence;

60 + 90 + <W = 180

<W = 180 - 150

<W =  30 degrees

Hence the angle measures of triangle VUW are m∠V = 90°, m∠U = 60°, m∠W = 30°

The length of the rectangle is increased by 10%.
The width of the rectangle is increased by 5%.
Find the percentage increase in the perimeter of the rectangle.

Answers

answer

15.5%

Step-by-step explanation:

length = 30

30+10%=33

breadth=20

20+5%=21

area of rectangle = length × breadth

600² centimeters = 30 × 20

693² centimeters = 33 × 21

Increase = 15.5%

a motor bike travels 240 km in 4 hours. How long will it take to travel 450 km​

Answers

Answer:

7 hours and 30 minutes

Step-by-step explanation:

[tex]240 \div 4 = 60km \: per \: h[/tex]

[tex]450 \div 60 = 7.5 = 7h \: 30min[/tex]

It will take motor bike 7.5 hours to cover 450 Km of distance.

What is Speed in Kinematics?

Speed of a body is defined as the distance travelled by it per unit time taken to cover the distance.

Mathematically-

S = Δd/Δt  or   S = {d(2) - d(1)}/{t(2) - t(1)}

It is a scalar quantity as it only has magnitude and no direction.

Given is a motor bike travels 240 km ins 4 hours.

We can calculate the speed of the bike as -

s = 240/4 = 60 Km/hr

Then, the time taken to cover 450 Km will be -

t = 450/60

t = 7.5 hours

Therefore, it will take motor bike 7.5 hours to cover 450 Km of distance.

The boiling point of water is 100 degrees Celsius. Write an inequality to represent a pot of water that is not boiling.​

Answers

Answer: x < 100 , where x  = the temperature of a pot of water ( in degrees Celsius).

Step-by-step explanation:

The boiling point of water is 100 degrees Celsius.

The temperature of water that is not boiling must be less than 100 degrees Celsius.

Let x  be the temperature of a pot of water ( in degrees Celsius).

Then, as per given,

x < 100

I need help on how to solve 8 × 6 + (12 - 4) ÷ 2​

Answers

Answer:

42

Step-by-step explanation:

8x6+(8)/2

48+4

42

Answer:

52

Step-by-step explanation:

So in order to answer this question we are going to have to use the order of operations by starting with the parenthesis of subtracting 4 from 12:

8 × 6 + (12 - 4) ÷ 2​

12 - 4 = 8

Now the equation looks like this:

8 × 6 + 8 ÷ 2

Now we multiply 8 by 6 and dividing 8 by 2 because multiplication and division come first​:

8 * 6 = 48

8/2 = 4

So the equation looks like this:

48 + 4

We now add them together to get our answer:

48 + 4 = 52

So the answer to this equation is 8 × 6 + (12 - 4) ÷ 2​ = 52
