​ Quadrilateral ABCD ​ is inscribed in this circle.
Ilya [14]
Hello,

When you have an inscribed quadrilateral, the opposite sides are supplementary.

So you can write and solve the following equation.
x + 6x + 19 = 180
7x + 19 = 180
7x = 161
x = 23

Now, plug in 23 for X and we will find the measurement of B.
6(23) + 19
138 + 19
157

The measure of angle B is 157 degrees. (The picture is not drawn to scale)

Good luck,

13-5m=4-6m show work please
Vesna [10]
First subtract 4 from both sides
13 - 4 - 5m = - 6m

then simplify
9 - 5m = - 6m

add -5 to both sides
9 = - m

since a variable shouldn't be negative the answer should be
m = - 9

(I prefer having the variable on the left side)
