When a quadrilateral is inscribed in a circle, the opposite angles are supplementary.
x + 6x + 19 = 180
7x + 19 = 180
7x = 161
x = 23

Now solve for B.
6(23) + 19 = B
138 + 19 = B
157 = B

The measure of angle B is 157 degrees

Hope this helps =)

What is the current density of the solution a/m2

Jlenok [28]

Current density of solution a/m2 is given below

Step-by-step explanation:

Current density is the measure of current generated per unit surface area of electrode.

Eg: In microbial fuel cell/fuel cells, if you are using electrode with size of 5cm x 2cm and current produced is 200mA, then current density will be,

CD= Current/(projected area of electrode)

area of rectangle= LxB= 5cm x 2cm =10cm2

CD= 200mA/10cm2

CD= 20mA/cm2

Your Current will be 200mA.

Current density will be 20mA/cm2.
