Question

find the Value of the x in each case​

Answer 1

Answer:

1) 55

2) 30

3) 30

Step-by-step explanation:

1) Angle EAF = Angle BAC = 60

Angle ACB = 180-115 = 65

In a triangle, sum of all angles is 180

Therefore x = 180 - (60+65) = 55

2)Triangle ABC is right angle, so sum of the 2 acute angles = 90

=> Angle ABC = 90-40 = 50

In triangle BDE, x = 180-(100+50) = 30

3)In triangle ABE, Angle AEB = 180-(75+65)

= 180 - 140 = 40

Angle AEB = Angle CED = 40

In triangle CDE, x = 180-(110+40)

=>180 - 150

=> 30

Answer 2

Answer:

Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.
