Step-by-step explanation:
supplementary angles means sum of them is 180°
8x+4+6x+64 = 180
14x+68 = 180
x = 8
angles are 68 and 112
Please, when you present a list of numbers, such as 4, 8, 16, ..., separate them with commas or semicolons: 4, 8, 16, ...
If x^2 + y^2 = 16, then 16 represents r^2, and r = 4. r cannot be negative in this type of problem.
