Answer:

Step-by-step explanation:
<h3><u>Statement:</u></h3>
- If a quadrilateral is inscribed in a circle, the opposite angles add up to 180 degrees.
<h3><u>According to the statement:</u></h3>
∠D + 88° = 180°
<em>Subtract </em>88 to both sides
∠D = 180° - 88°
∠D = 92°

Answer for 1st set:
m∠1=105° and m∠2=75°
Breakdown:
You're given one angle of 75°. That one angle is equal to m∠2. Since m∠2 is making a linear pair with m∠1, you take 180° (Straight line) and take 75° from it.
180-75=105
Answer for 2nd set:
m∠1=130° and m∠2=50°
Breakdown:
Using the same logic as before, linear pair, blah-blah-blah, you're given 130.
180-130=50
Answer:
you need 2,400 tiles
Step-by-step explanation:
400x300=120,000 thats how big the area of the room will be.
120,000÷50=2400
