An angle measures 78° more than the measure of its supplementary angle. what is the measure of each angle?

51° and 129°

Step-by-step explanation:

let x be the measure of one angle then x + 78 is the measure of the other

Supplementary angles sum to 180°, hence

x + x + 78 = 180, that is

2x + 78 = 180 ( subtract 78 from both sides )

2x = 102 ( divide both sides by 2 )

x = 51

Hence

the angles are 51° and 51 + 78 = 129°

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y
