Question

Which two equations can be used to determine the measure of these two angles if the total sum is 90 degrees? (1 point) Responses (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

Answer 1

The two equations that can be used to determine the measure of these two angles if the total sum is 90 degrees are:

(7x - 9) - 4x = 90
and
3x - 9 = 90

These equations represent different ways of expressing the relationship between the angles and their measures, and can be used to find the value of x and ultimately determine the measures of the angles.
