Answer:
A
Step-by-step explanation:
The measure of angle D can be found using the Interior Angle Sum of a Triangle.
The angles of a triangle add to 180. This means:
90 + 21 + x = 180.
111 + x = 180
x = 69
The solution is A.
Angle B is smaller than Angle D which means CD will be smaller than BC.
Answer:
true, they can form a triangle.
Step-by-step explanation:
since, sum of two sides is greater than the third side in any case and the difference between two sides is smaller than the third one in all cases.
I don't know the answer but my tip would be to split the shape the way I did it, find the lengths of each side, and then find the area for each individual shape.
Then add all the areas together.
The "one head and one tail" would be my best guess because you get one of each outcome, whereas the other two outcomes are two of the same outcome.
