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 |
