Question

Formulate a pair of linear equation in two variable for the given data.
Two angles are supplementary, the larger is 15° less than twice the measure of the smaller angle.​

Answer 1

Answer:

let the angles be x and y.

supplementary angle = 180.

smaller angle = x

larger angle = 2x - 15. =y.

x + y =180

Answer 2

let th the larger angle be x let the smaller angle be y . x + y = 180

given that larger angle is 15

degrees less than the twice of the smaller angle

x = 2y - 15
