Answer:
45°
Step-by-step explanation:
three angles in a triangle sum up to 180
90° + a + a = 180°
90° + 2a = 180°
2a = 180°-90°
2a = 90°
a = 45°

Answer:
12
Step-by-step explanation:
0 + 1 + 2 + 3+ 4 + 5 + 6 + 7 +8 + 9 + 10 + 11 seems to equal 66. That means there are 11 + 1 = 12 people (don’t forget to count the person who shakes 0 hands)
I would add like terms, meaning subtract 6.4 from both sides.
3.5n = 36.1
