Answer:
m∠A ≈ 43°
m∠B ≈ 55°
mBC ≈ 20
Step-by-step explanation:
Law of Sines:
Step 1: Find m∠B
Step 2: Solve for ∠B
29sinB = 24sin82°
sinB = 24sin82°/29
B = sin⁻¹(24sin82°/29)
B = 55.038°
Step 3: Find m∠A
180 - (55.038 + 82)
180 - 137.038
m∠A = 42.962°
Step 4: Find BC
Step 5: Solve for BC
29sin42.962° = BCsin82°
BC = 29sin42.962°/sin82°
BC = 19.9581
Answer:
Semiannual payment = $ 1391.37
Total payment = $ 8348.22
Interest paid = $ 848.22
Step-by-step explanation:
Since, the semiannual payment formula of a loan,
Where,
PV = present value of the loan,
n = number of semiannual payments,
r = annual rate,
Here, PV = 7500, r = 6.3% =0.063, n = 6,
By substituting the value,
The semiannual payment would be,
Also, total payment = semiannual payment × total semiannual periods
= 1391.37 × 6
= $ 8348.22,
Also, the interest paid = total payment - present value
= 8348.22 - 7500
= $ 848.22
