Question

in a rectangle ABCD AB is equals to 40 cm angle BAC is equals to 30 degree then side BC is equal to?​

Answer 1

Answer:

A.T.Q

We have rectangle ABCD

JoinAC

We know that diagnoals of rectangle are of 90°

so by this

by trigonometry

tan30°=BC/AB

1/√3=BC/40

BC=40/√3

Answer 2

Answer:

It cannot be a rectangle with an angle 30 degrees

Step-by-step explanation:

• A shape with four right angles, or 90 degrees, is a rectangle.
• A rectangle cannot be identified by an angle is 30 degrees.
• The length of BC cannot be calculated without more details about the issue because the information provided is insufficient to address the issue.
• We would need more details, such as the size of the other angles or the length of the other sides, in order to determine the length of BC in this situation.
• It cannot be a rectangle with an angle 30 degrees.
