From the given figures, find the value of x.1100xGx +8 (2x-33)5/69° |
|
Answer» i) AOB is straight line so sum of angles will be 180°. 3x + 8 + 2x - 33 = 180° 5x - 25 = 180° 5x = 180° + 25° = 205° x = 41° ii)Total sum of angle is 360°So, 110° + 51° + 69° + x = 360° x + 230° = 360° x = 360° - 230° x = 130° |

The area of four walls of a room is 120 m2. If the length of the room is twice its breadth andhroad and 34 m high. It has two doors, each measurinthe height is 4 m, find the area of the floor. |
|
Answer» Let the breadth of the room is xand therefore length will be 2x(given that Length is double of breadth)Height of the room is 4mNow given that area of four walls is 120m^2 Now area of 2 walls= 2*(length*height)=2(2x*4) =(16x)m^2and area of another 2 walls= 2*(breadth*height)=2(x*4)=(8x)m^2Now,So, area of 4 walls= Area of 2 walls+ Area of another 2walls120m^2= (16x)m^2+(8x)m^2120=24xx=120/24x=5Therefore, breadth= x=5m and length=2x=10mSo, area of floor =length*breadth= 5*10=50m^2 |
