EMERGENCY PLEASE HELP

Step-by-step explanation:

here <D+<B=180

sum of two opposite angle of the cyclic quadrilateral is 180

x+28=180

x=180-28=152°

angle A=x-36=152-36=116°

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
