Area of the sector = 62.86 unit²

Step-by-step explanation:

Given:

Radius = 10 unit

Central angle = 2/5π radians

Find:

Area of the sector = ?

Computation:

$Area =\frac{1}{2}r^2 \theta\\\\ Area =\frac{1}{2}(10)^2(\frac{2 \pi}{5} )\\\\Area =\frac{1}{2}(100)(1.257)\\\\Area =62.86$

Area of the sector = 62.86 unit²

Step-by-step explanation:

One root = -5

We know ,

Product of roots = c/a-5 * x = -10k / k -5x = -10 x = 2

Other root is 2 .
