Question

5. Two adjacent angles of a parallelogram are in the ratio 2:1. Find the measure of each angle
6. Findthe greatest perfect square of 5 digits numbers.
7. Find the smallest number by which 3888 must be multiplied so that the product is a perfect​

Answer 1

Answer:

5.Let the first side be 2x

Second side be 1x

2x+1x=180 (sum of two adjacent sides is 180)

3x=180

x=180÷3

×=60

first side=2x

=2×60

=120

Second side= 1x

=1×60

=60

As we all know opposite sides are equal in parallelogram so,

first side= third side

third side = 120

second side = fourth side

fourth side= 60

6. The greatest perfect square of 5 digits is 99856 .

7. When we do prime factorisation of 3888 so we get

3888=2×2×3×3×2×2×3×3×3

If we multiply 3888 by 3 so we also have pair of 3

3888×3=11664
