50
Since a triangle always equals 180, you add 68 and 62, which gets you 130.
180 - 130 = 50
Hope this helps!

General Formulas and Concepts:
Pre-Alg
- Order of Operations: BPEMDAS
Step-by-step explanation:
Step 1: Define
f(x) = -3x^2 + 9x
f(-2) is x = -2
Step 2: Solve
1. Substitute: f(-2) = -3(-2)^2 + 9(-2)
2. Evaluate: f(-2) = -3(4) + 9(-2)
3. Multiply: f(-2) = -12 - 18
4. Add: f(-2) = -30
Answer:
16 the answer is 1, 4, 5, 6, yeah good answer
0. The two lines are parallel because they have the same slope. You can find this by using the slope formula.
