Answer:
Step-by-step explanation:
<u>The two angles of the triangle ADB are:</u>
- m∠A/2 and m∠B/2 or
- α/2 and β/2
<u>The three interior angles add to 180°, so the missing angle is:</u>
- m∠ADB = 180° - 1/2(α + β)
Answer:
90 degree angle because a right angle is always 90 degrees
<em>9/20+5/12=14/32/2 equals a over all 7/16</em>
