Which statement regarding the interior and exterior angles of a triangle is always true? An exterior angle is supplementary to the adjacent interior angle.
An adjacent interior angle is supplementary to a remote interior angle.
A remote interior angle is congruent to the exterior angle.
An exterior angle is supplementary to a remote interior angle.

The answer would be A.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
