Question

The angles of a quadrilateral are x,x+10,expand 3x find each angle

Answer 1

Answer:

x=70

x+10=80

3x=210

Step-by-step explanation:

Let the sides of quadrilateral be x,x+10,3x

We can split 3x as x and 2x

Sum of angles of a quadrilateral is 360

So,

x+x+10+x+2x=360

5x+10=360

5x=360-10

5x=350

x=350/5

• x=70
• x+10=70+10

=80

• 3x=70*3

=210

Hope this helps you
