Which angles form a linear pair?

Mathematics
2 answers:
kirza4 [7]3 years ago

Answer:

∠MRN and ∠NRO is a linear pair.

Step-by-step explanation:

Linear pair : A pair of adjacent angles formed by two intersecting lines is called linear pair. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

A )∠PRL and ∠LRM

According to the definition ∠PRL and ∠LRM is not linear pair .

B)∠ORP and ∠MRN

These angles are formed by the intersection of line OM and PN.

But these angles are vertical angles not adjacent.

Thus ∠ORP and ∠MRN is not a linear pair .

C) ∠MRN and ∠NRO

∠MRN and ∠NRO are formed by the two intersecting lines MO and NP.

Since they these angles are true to the definition.

Thus ∠MRN and ∠NRO is a linear pair.

D)∠LRP and ∠ORP

According to the definition ∠LRP and ∠ORP is not a linear pair .

Hence ∠MRN and ∠NRO is a linear pair.

Faiz's total online shipping bill comes to £45.71.
larisa [96]

Given:

Faiz's total online shipping bill comes to £45.71.

He then receives discount of £15.90.

To find:

How much does he have to finally pay after the discount?

Solution:

We have,

Amount of bill = £45.71

Discount amount = £15.90

Now,

Final payment = Amount of bill - Discount amount

                        =  £45.71 - £15.90

                        = £29.81

Therefore, Faiz's have tp pay £29.81 after discount.

The measure of angle t is 60 degrees. What is the x-coordinate of the point where the terminal side intersects the unit circle?
Ivenika [448]

Answer:

\frac{1}{2},

Step-by-step explanation:

Please find the attached image of unit circle.

We have been given that the measure of angle t is 60 degrees. We are asked to find the x-coordinate of the point where the terminal side intersects the unit circle.

We know that x-coordinate on unit circle represents cosine and y-coordinate represents sine of a given angle.

We can see from our attachment that x-coordinate of the point at angle 60 degrees is \frac{1}{2}, therefore, x-coordinate of the angle of 60 degrees, where the terminal side intersects the unit circle is \frac{1}{2}.

During a week in January in Denver, CO, the daily high temperatures were -2˚F, 12˚F, 5˚F, -4˚F, 20˚F, 16˚F, and -12˚F. Write an
Triss [41]

Answer:

20˚F - (-12˚F)

Step-by-step explanation:

Highest temperature of the week = 20˚F

Lowest temperature of the week = -12˚F

The difference between the highest and the lowest temperature actually means to subtract the lowest from the highest temperature.

The required expression is;

20˚F - (-12˚F)

Demichael orders a set of numbers on his
Andru [333]

The numbers are ordered, such that the first number (the largest one) is:

(5 + 1/2)

And the last number (the smaller one) is (5 + 1/3). Only by knowing this, we will see that the correct options are A and C.

We want to see which of the following numbers is not on the list:

A) √25

B) 5.45

C) 5 12  

D) 5.34

One of these numbers can only be in the list if it is larger than  (5 + 1/3) and smaller than (5 + 1/2).

To see this easier, let´s rewrite both of these:

5 + 1/2 = 5 + 0.5 = 5.5

5 + 1/3 = 5 + 0.33 = 5.33

Then if a number is smaller than 5.33, the number can't be in the list.

Here we can see two numbers that are smaller than 5.33

These are:

Option A) √25 = 5 < 5.33

Option C) 5.12 < 5.33

And there is no number larger than 5.5

Concluding, the numbers that are not in Demichael's list are:

√25 and 5.12
