answer as soon as possible, please! !algebra! 2¹⁵ x 8¹⁹ x 2⁴ x 8¹⁰ a. 2¹⁹ x 8²⁹ b. 4⁶⁰ x 64¹⁹⁰ c. 2⁶⁰ x 8¹⁹⁰ d. 4¹⁹ x 16²⁹ and the x's are multiplication not variables
Supplementary means two angles add up to 180 degrees. Let's say A+B=180. Since we know what A is, we can substitute that in, B+80=180. Now solve. B=100
