Please Help!!<br> It's urgent :)
Paha777 [63]

Answer:

hope this helps

Step-by-step explanation:

For a.) I would do the simplist example possible and make all 3 angles equal. So you would divide 180° degrees by 3. This gives you 60° for each angle. That is still acute.

b.) complementary angles mean they add up to 90°

If one has to be greater than 45° you can so 68° and 22°.

c.) 100 - 10,10; 20,5; 50,2; 4,25

You can choose any pair for the length and width of the ones I put above. :)

d.) angle ABC can equal 32° and angle CBD can be 10°
