Answer:
1. Use the distance formula and midpoint formula
2a. Learn the properties of an orthocenter
2b. Write a conjecture and then verify if it's true for acute and right triangles
3. Prove that D is not equidistant from A to C
Step-by-step explanation:
From here, we need to start by making an equation:
We know that it has a common difference of 6, thus, the slope is -6.
22 = -6(6) + b
b = 58
So we have our equation:

Let's plug 50 in and we get
-242
Answer:

Step-by-step explanation:
By Inscribed Angle Theorem, the value of an inscribed angle enclosed by an arc is the half the value of that arc.
⇒ ∠RPQ = 108°/2
⇒ ∠RPQ = 54°
Answer: 80
Step-by-step explanation:
Looking at the ratios in the table, the number of days to number of questions is 1:5 (4x5=20; 8x5=40;11x5=55). So for 16 days it will be 16x5=80
