1) "a" and 60° are vertical angles, hence equal. a = 60°
2) "b" is the supplement to 60°, so is 180° - 60° = 120°. b = 120°
3) "d" is the supplement to 65°, so is 180° - 65° = 115°. d = 115°
4) "e" and 65° are vertical angles, hence equal. e = 65°
5) "g" is the supplement to 55°, so is 180° - 55° = 125°. g = 125°
6) "h" and 55° are vertical angles, hence equal. h = 55°
X=5 is the answer to this equation. you multiply 5 by 3 which is 15 and then add 5, giving you 20.
First, we know that a² + b² = c². We will just be using this in a different way! b² = c² - a²
b² = 32² - 28²
b² = 1024 - 784
b² = 240
b = 15.49
Hope this helps!
