One of the other angles is 72. Vertically opposite angles are equal.
Two angles that are side by side on this arrangement are supplementary.
That means they are to 180
x + 72 = 180
x = 180 - 72
x = 108
Answer
the for angles are
72 + 72 + 108 + 108
Answer:
A Quadrilateral is a 4 sided figure. In other words any shape that has 4 sides is a quadrilateral for example square, rectangle, trapezium etc
Step-by-step explanation:
3 / 5 = (x+1) / (y-2)
↓
↓ multiply by 5 / 3
↓
1 = 5 * (x+1) / 3 * (y-2)
↓
↓ move and simplify
↓
5x + 5 = 3y - 6
↓
↓ minus 5
↓
5x = 3y - 11
↓
↓ divide by 5
↓
Answer : x = (3y - 11) / 5
