Can someone me with the last question?

  1/2

Step-by-step explanation:

The question appears to be asking only for the slope. The given point seems to be irrelevant.

The slope of the perpendicular line is the opposite of the reciprocal of the slope of the given line. That slope is the coefficient of x in the line's equation: -2. The opposite reciprocal of -2 is ...

  -1/(-2) = 1/2

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
