Question

Diagram NOT accurately drawn

In this quadrilateral, the sizes of the angles, in degrees, are
x + 10
2x
2x
50
(a) Use this information to write down an equation in terms ofx.
.
(b) Work out the value of x.​

Answer 1

5x+60 = 360, x = 60

Explanation:

Answer 2

5x+60 = 360, x = 60

Explanation:

Ok, so the key to this problem is to realize that all angles added up in a quadrilateral give you 360 degrees. This means that x+10 + 2x + 2x + 50 = 360. Then we can just simplify to 5x + 60 = 360, 5x = 300, and x = 60.
