Question

Which two equations can be used to determine the measure of these two angles?
its a right angle split in two
on angle is (7x-9) the other is 4x
what are the two options

(7x−9)−4x=90
open paren 7 x minus 9 close paren minus 4 x is equal to 90

(7x−9)+4x=180
open paren 7 x minus 9 close paren plus 4 x is equal to 180

(7x−9)+4x=90
open paren 7 x minus 9 close paren plus 4 x is equal to 90

11x−9=90
11 x minus 9 is equal to 90

3x−9=90
3 x minus 9 is equal to 90

11x−9=180
11 x minus 9 is equal to 180

Answer 1

are you sure? and why would it be this (7x−9)+4x=180 if is a 90 degree angle shape

Answer 2

The correct equations are:

(7x−9)+4x=180
(7x−9)+4x=90

Answer 3

You are correct, I apologize for the error. Since the angle is a right angle, the sum of the two angles should be 90 degrees.

The correct equations are:

(7x−9) + 4x = 90
