Question

A campground site is in the shape of a
convex quadrilateral. Three sides of the
campground form two right angles. The
third interior angle measures 10° less
than the fourth angle. Find the measure
of each interior angle.

Answer 1

Answer:

  90°, 90°, 85°, 95°

Step-by-step explanation:

The sum of the two unknown angles is 180°. If x is the smaller one, that means ...

  x + (x+10°) = 180°

  2x = 170° . . . . . . . subtract 10°

  x = 85°

The interior angles are 90°, 90°, 85°, and 95°.
