Question

Two supplementary angles differ by 70. find the measure of each angle

plz answer with steps​

Answer 1

Let one of the angles be x.

Another angle = (180-x) [ because another supplementary angle will be the difference this angle and 180 degree]

According to question,

x-(180-x)= 70

x-180+x=70. [ removing bracket, signs changed]

2x=70+180

x= 150/2

x= 75 degree. [150/2= 75 degree]

Another angle= (180-75)

= 105 degree

one angle = 75 degree

Another angle= 105 degree

Answer 2

Answer:

first angle is 55 degree and the second angle is 125 degree

Step-by-step explanation:

supplementary angles measures 180 degrees........

let one of the angles be x......

so the other angle is x+70

according to the question,

x + x +70 = 180

so,

2x + 70 = 180

2x = 180 - 70

2x = 110

x = 110/2

x = 55

so, first angle = 55

second angle is x + 70

so 55 + 70 = 125

hope it helps.......
