Question

The measure of angle 1 is five less than four times the measure of angle 2. If angle 1 and angle 2 form a linear pair, what are their measures?

Answer 1

what'ss linear pair?

Answer 2

Linear pair is also another expression that says that angle 1 and angle 2 are supplementary i.e. their measures add up to 180 degrees

Answer 3

really?

Answer 4

so do I do
2(4x-5)=180?

Answer 5

angle 1 = 4( angle 2) - 5

4( angle 2) - 5 + angle 2 = 180

Answer 6

You need to write up two equation relating angle 1 and angle 2, one that is just saying that Angle 1 is equal to 4 times angle 2 minus 5, and another saying that they are supplementary, and solve the resulting linear system (by substitution or elimination)

Answer 7

x = angle 1
y= angle 2

x = 4y - 5
x + y = 180
like that?

Answer 8

right
