Hey!

-------------------------------------------------

Question #1:

To make a straight line two angles need to add up and equal 180°

If m∠2 equals 146°

Then m∠7 equals 180 - 146°

Answer: 34°

-------------------------------------------------

Question #2:

To make a straight line two angles need to add up and equal 180°

If m∠8 equals 49°

Then m∠7 equals 180 - 49 = 131°

Since L1 and L2 are parallel we can see that all the angles are the same each line.

Answers:

1 is 131°

2 is 49°

3 is 131°

4 is 49°

5 is 131°

6 is 49°

7 is 131°

-------------------------------------------------

After solving both questions you are correct!

-------------------------------------------------

Hope This Helped! Good Luck!

First picture:

2 and 7 are alternate exterior angles, which when added together need to equal 180 degrees.

Angle 7 = 180 - 146 = 34

Answer is B.34

Second picture:

Angle 8 = 48

Angle 8  + angle 7 = 180

Angle 7 = 180 - 49 =  131

Angle 5 and angle 7 are vertical angle, so angle 5 = angle 7 = 131

Angle 6 is a vertical angle to angle 8 so = 49

Angle 1 = angle 5 = 131

Angle 2 = angle 6 = 49

Angle 3 = angle 7 = 131

Angle 4 = angle 8 = 49

A scale drawing for an apartment shown below in the drawing is 2 cm represent 5m
rjkz [21]

Firstly, found out a square that is 7cm long and 5cm wide, you get the 7 from adding 5+2 across the top. Don't forget that, 2cm = 5m so you get the real area we need to work out how many meters are in each length.

So, firstly you know that in 1 cm there is 2.5m, with this information you can then do 7x2.5 to get the distance across the top in meters. That gives you 17.5 megers for the top and 5x2.5 = 12.5m.

After finding that, you have to find the area of this square, so you do 17.5m x 12.5m = 218.75m^2 for the biggest square, that's the total area however we want the bedroom area.

Therefore we have to workout how much area is in the living room and take that away from the total amount. Since we found out how many meters are in the 5cm we can use that here again. 12.5m x 12.5m = 156.25m^2 with this we do 218.75m^2 - 156.25m^2 = 62.5m^2 is for the bedroom and small empty space. now we just need to find the small empty space.

To do that, we do 5-4 which leave us with 1 cm and we already know it's across length is 2, with the information provided and stated we know that it's 2.5m x 5m = 12.5m^2

Then finally we do 62.5m^2 - 12.5m^2 to get the bedroom area. <u>50m^2</u>

A circle is never a square?
Nookie1986 [14]

Answer:

never

Step-by-step explanation:

Since the area of the circle will always be a transcendental number and the area of a square has to be an integer, this can never happen in a finite number of steps. Therefore, you cannot square a circle
