Total area = 9 x5 =45
Total area = (6+3)(4+1)=24+6+12+3=45
i say C. -5, -2, 1, 4, 7 is your answer for question 1.
and for question 2 i think is E. -6, -4, -2, 0, 2.
<u>Ratio of two angles are 6:13.</u>
So, let the one angle be and another be
As we know that,
Sum of all interior angles of a quadrilateral =
So let's sum up the given angles,
Hence,
So, First angle
Second angle
