Question

АВСD-прямоугольная трапеция, один из углов равен 20 Градусов.Найти все остальные углы

Answer 1

так как прямоугольная трапеция2 угла будут равны 90 градусам

90+90+20=200

общая сумма градусов равно 360

360-200=160

Answer 2

т.к сумма углов любой трапеции равна 360 градусов ,т к угол А и В=90градусов,а угол D равен 20 градусов ,то угол С =360-(90+90+20)=160градусов

ответ А=В=90
С=160 

Answer 3

Finding the Other Angles of a Trapezoid

To find the other angles of a trapezoid ABCD, where one of the angles is 20 degrees, we can use the properties of a trapezoid.

A trapezoid is a quadrilateral with one pair of parallel sides. In this case, we have sides AB and CD parallel to each other.

Let's denote the angles of the trapezoid as follows: - Angle A = 90 degrees - Angle B = 90 degrees - Angle C = unknown - Angle D = 20 degrees

To find angle C, we can use the fact that the sum of the angles in a quadrilateral is 360 degrees.

From source we can see that the sum of the angles in a trapezoid is 360 degrees. Therefore, we can calculate angle C as follows:

360 - 90 - 90 - 20 = 160 degrees

So, angle C is equal to 160 degrees.

To summarize, the angles of the trapezoid ABCD are as follows: - Angle A = 90 degrees - Angle B = 90 degrees - Angle C = 160 degrees - Angle D = 20 degrees
