Answer:
x = 25 B = 65˙ C = 50˙
Step-by-step explanation:
Triangle Sum- All three angles in a triangle add up to 180˙
65 + (3x - 10) + (2x) = 180
65 - 10 +3x + 2x = 180 Combine like terms
55 + 5x = 180 Move the 55 over to combine w/180.
- 55 -55
5x = 125 Divide by 5
5 5
x = 25 Answer
B C
(3x - 10) (2x)
(3*25 - 10) (2* 25)
65˙ 50˙
