Answer:
Line 3 is incorrect; we don't know anything about the lengths of HG, FG, HE, and EF, so this line is not valid based on the given information.
Step-by-step explanation:
In the Noah's poof of the construction, segment EG would divide angle FGH into two equal parts, which makes line 2 to be valid. i.e <EGH ≅ <EGF. And it can also be observed that line 4 is a valid theorem in proving the congruent nature of triangles.
But line 3 is not valid because of the condition of the statement. Furthermore, segments FG, EG, HG, HE and FE may not be congruent. Thus, the condition of the statement in line 3 is incorrect.
Answer:
The value of x is 80°
Step-by-step explanation:
Explanation is shown in the picture.
x = 2 × 40°
= 80°
Answer:
= 0.05P - 150
Step-by-step explanation:
Let P(t) be the balance of the loan at time t years,
Let P(t) will satisfy 
where r = annual interest rate
R = per year payment rate
R = $150/year
r =
= 0.05 
Now we have the following picture,
Interest Balance Payment
5% ⇒ P(t) ⇒ $150/year
(0.05)
Therefore, a linear ODE satisfied by P(t) is given by
= 0.05P - 150
