$\sqrt{9+b^2+c^2}\,\text{units}$

Step-by-step explanation:

The distance formula tells you the distance d between the points (0, 0, 0) and (-3, -b, c) is ...

d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²) = √((-3-0)² +(-b-0)² +(c-0)²)

= √(9 +b² +c²)

Option B

Step-by-step explanation:

Given that the vertex angle of an isosceles triangle measures

$40^{o}$

We have to find the measure of base angle.

Given that isosceles triangle we find that two base angles are equal.

Let x be the one of the base angle.

The sum of three triangles is 180 degrees.

x+x+40=180

$2x+40=180\\2x=140\\x=70^{o}$

Option B is right.
