Question

The measure of Angle D is degrees. O=41 degrees

Answer 1

Answer:

49°

Step-by-step explanation:

$m\angle D = 180 \degree - (90 + 41) \degree \\ \\ = 180 \degree - 131\degree \\ \\ = 49 \degree$

Answer 2

Answer:

49°

Step-by-step explanation:

O=41° and G=90° (because it is a right angle).  The sum of the interior angles of a triangle is 180°.  So, add the known angles, 41°+90°=131°.  Since the sum of all three angles needs to be 180°, subtract the known angles from the total, 180°-131°=49°, to find the unknown angle.
