Construct a parallelogram whose diagonals are 5.4 cm and 6.2 cm and an angle between
them is 70°.​

15.73 cm²

Step-by-step explanation:

Construct a parallelogram whose diagonals are 5.4 cm and 6.2 cm and an angle between them is 70°.​

To construct the parallelogram, we find the Area of the parallelogram.

Area of a parallelogram = ½ × d1 × d2 × sin (y)

Where

d1 = Diagonal 1 = 5.4 cm

d2 = Diagonal 2 = 6.2 cm

y = Angle between them = 70°

Area of the parallelogram =

1/2 × 5.4 × 6.2 × sin 70

= 15.730454472 cm²

Approximately = 15.73 cm²

answer: ask

step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
