Answer:
(a) w = 13
Step-by-step explanation:
You have a regular quadrilateral with interior angle measure (6w+13)°, and you want the value of w to the nearest integer.
Regular quadrilateral
A regular quadrilateral is a square. Its interior angles are 90°, so we have ...
6w +13 = 90
6w = 77
w = 12.833...
w ≈ 13
The value of w to the nearest whole number is 13.
