Question

the angles of a quardrilateral are x digrees, (x+10​

Answer 1

Answer:

Answer:

58 degree

sum of the interior angles of a quadrilateral = 360 degree

angle A = x

angle B = x-10

angle C = x+30

angle D = 2x

this means : x+(x-10)+(x+30)+(2x) = 360 degree

                    3x+2x+20 = 360 degree

                     5x = 340 degree

                     x = 68 degree

angle A= x = 68 degree

angle B= x-10= 58 degree

angle C= x+30=98 degree

angle D= 2x= 136 degree

clearly angle B is the smallest

therefore smallest angle is 58 degree...

Answer 2

Animals are adapted to survive in the conditions in which they live. Features and habits which help them to adapt to their surroundings are the result of evolution. So, to survive in a particular type of climate the animals must have certain adapted features. This is the reason we find animals of certain kind living in particular climatic conditions. For example, animals in the polar region are adapted to the extremely cold climate. They have special characteristics, such as white fur, strong sense of smell, a layer of fat under the skin, wide and large paws for swimming and walking in snow etc
