Part a: Option c: 3x+90+x-14=180

Part b: The value of x is 26

Explanation:

Part a:

Option a: 3x+x-14=180

Since, adding all the angles in the straight line results in 180°, and only two of the three angles were added in the equation to find the value of x.

Thus, the equation 3x+x-14=180 cannot be used to determine the value of x.

Hence, Option a is not the correct answer.

Option b: 3x+90+x-14=90

Adding all the angles in the straight line results in 180°.

Thus, adding all the angles does not equals to 90°

Hence, the equation 3x+90+x-14=90 cannot be used to determine the value of x.

Hence, option b is not the correct answer.

Option c: 3x+90+x-14=180

Since, the straight line is 180° and thus adding the angles in this straight line will result in 180°

Thus, the angles in this straight line are 3x, 90° and x-14.

Hence, adding these angles will result in 180°

Thus, the equation becomes

3x+90+x-14=180

Hence, the equation used to determine the value of x is 3x+90+x-14=180

Thus, Option c is the correct answer.

Option d: 4x+90=360

Adding all the angles in the straight line results in 180°.

Since, not all the three angles were added in this equation and the equation equals to 180°

Hence,  the equation 4x+90=360 cannot be used to determine the value of x.

Thus, Option d is not the correct answer.

Part b:

To determine the value of x, we shall add all the angles of the equation 3x+90+x-14=180

Thus, we get,

4x+76=180

Subtracting both sides by 76,

4x=104

Dividing both sides by 4, we get,

x=26

Thus, the value of x is 26.

Given: If you live in Orlando, then you live in Florida.
____ [38]

Answer:

The law of detachment and syllogism is valid here

Explanation:

The law of detachment and syllogism is associated with inductive reasoning. This law states that a conclusion is valid if the premise or hypothesis is valid, therefore if a then b. In others a results in b.

The law of detachment is denoted

[(a→b)∧a]→b

The law of syllogism derives from the law of detachment. Syllogism says that if a results in b and b results in c, then a results in c. In other words since a causes b and b causes c, then if a then c.

It is denoted

[(a→b)∧(b→c)]→(a→c)

In the above example, given: If you live in Orlando, then you live in Florida

Morgan does not live in Orlando, therefore it is concluded that he does not live in Florida

-10 F is colder than -4 degrees?
Aleks04 [339]

Answer: yes, it is a smaller temperature, which means that is "colder"

Step-by-step explanation:

I guess that the question is:

Is -10°F colder than - 4°C?

Ok, when we have a temperature T in Celcius, the equation to transform this quantity to the Fahrenheit scale is:

T' = (T*9/5) + 32°

Replacing T by the temperature in celcius, we get:

T' = (-4°*9/5) + 32° = 24.8°F

This means that -4°C is equivalent to 24.8°F

And -10°F is a smaller value than 24.8°F (which mean that is colder)

This implies that -10°F is colder than -4°C

Then the statement is true.

How 7,5,6 and 3 equal 75
____ [38]
Well first you do 7+5 to equal 12, and then you multiply 12 by 6 and get 72, then you add the 3 to get 75. 6(7+5)+3=75. Hope this helps!!

Can someone tell me how to find the Radius, Diameter, And Circumference Of a Circle?​
irakobra [83]
<h2>Answer:</h2>

<h3>Radius:</h3>

radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm.

<h3>Diameter:</h3>

2 times the radius is the circle's diameter.

<h3>Circumference:</h3>

The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.the formula for circumference of a circle is 2 x pi x r(radius).
