Here, Area of Square = a²
Area of parallelogram = a * b
Area of Trapezoid = (a+b)/2 * h
Area of Triangle = bh/2
In question, it says "half of the base" not bases, so most appropriate answer would be: Option D) Triangle
Hope this helps!
Answer: Never
Step-by-step explanation: Let me know if you need an explanation.
Answer: The measure of non-reflex ∠DOB is 108° and the measure of reflex ∠DOB is 252°.
Explanation:
It is given that the reflex angle ∠DOB has measure of 3.5y while the measure of ∠AOD is y.
From the given figure we can say that angle AOC and COB are supplementary angles and their sum is 180 because they are lies on a straight line.





Therefore the value of y is 72.



Therefore the reflex and is 252 degree.
The measure of non-reflex ∠DOB is,

Therefore, the measure of non-reflex ∠DOB is 108° and the measure of reflex ∠DOB is 252°.
The answer to the question is D
