The larger of two supplementary angles exceed the smaller by 18°, then larger angle will be​

Answer»

Answer:

81 & 99

Step-by-step explanation:

Let the smaller angle be x

∴ larger angle = smaller + 18 = x + 18

We know that SUPPLEMENTARY ANGLES ADD up to 180

∴(x) + (x + 18) = 180

2x + 18 = 180

2x = 180 - 18 = 162

∴x = 162/2 = 81

∴ larger angle = smaller + 18 = x + 18 = 81 + 18 = 99

CHECK 81 + 99 = 180
