Abby is constructing the inscribed circle for △jkl .
which construction could be her first step?
construct the perpendicular bisector of jk .
construct the angle bisector of ∠j .
construct a copy of ∠j that is adjacent to ∠k .
construct a perpendicular to kl that passes through point j.

Hence, the correct answer is:

Construct the angle bisector of ∠J .

Step-by-step explanation:

The steps for the construction of inscribed circle are:

The answer that best suits the construction among the given option is:

Construct the angle bisector of ∠J.

(Since first steps of the construction will be satisfied)

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
