The area of tapazuim is 400 cm 2 the distance between the parallel sides is 16 cm. if one of the parralel sides is 20 cm, find the length

the other parallel side is 30 cm

Step-by-step explanation:

here's the solution :-

let the other parallel side be x

now,

=》Area of trapezium =

=》( x + 20 ) × 8 = 400

=》x + 20 = 400 ÷ 8

=》x = 50 - 20

=》x = 30

so length of other parallel side = x = 30 cm

if you need just tell me and i will come to the rescue.

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
