Hi people, please any hint with this? i think if l move 270 degrees 1 space to the left l get -90 but... shows it as wrong thanks

you don't move it to the left, you move it up 1- there are no parentheses so it's a vertical shift

Step-by-step explanation:

a) move point up one- add 1 to y-coordinate

b) flip over x-axis (multiply y by -1)

da freeck kinda math is this just drop out

step-by-step explanation:

(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
