Answer:
Time = 6 years
Step-by-step explanation:
Data;
Simple interest = $507.50
Principal = $290
Rate = 12.5% = 12.5/100 = 0.125
Time = ?
To solve this question, we'll need to use the formula for simple interest
S.I = PRT / 100
Or
S.I = P(1 + RT)
S.I = simple interest
P = principal
R = rate
T = time
S.I = P(1 + RT)
507.50 = 290(1 + 0.125*T)
507.50 = (290 × 1) + (290 * 0.125T)
507.50 = 290 + 36.25T
Solve for T
36.25T = 507.50 - 290
36.25T = 217.50
T = 217.50 / 36.25
T = 6
The time tenure on the loan was 6 years
These problems are solved using the trigonometric function. Trigonometric functions provides the ratio of different sides of a right-angle triangle.
<h3>What are Trigonometric functions?</h3>
The trigonometric function refer to function that are periodic in nature and which lend insight to the relationship between angles and the sides of a triangle that is right angled.
The solutions to x in the respective problems is given as follows:
1st.) x = 5 /Sin(30°)
x = 10
!) sin(45°) = 4/x
x = 4/sin(45°)
x = 4√2
I) Cos(45°) = √3 / x
x = √3 / Cos(45°)
x = √6
E) Tan(60°)
= (3√3) / x
x = (3√3) / 3
W) It is to be noted that for right-triangle that is isosceles in nature, the angle made by the legs and the hypotenuse is always 45°.
x = 45°
N) x² + x² = (7√2)²
x = 7
V) Tan(60°) = 7 / x
x = 7√3/3
K) x² + x² = (9)²
x = 9/√2
Y) Sin(60°) = 7√3/x
x = 14
M) Sin(30°) = x/11
x = 11/2
T) Sin(45°) = x/√10
x = √5
A) x + 2x + 90° = 180°
x = 30°
O) Sin(45°) = √2 / x
x = 2
R) Tan(30°) = x / 4
x = 4/√3
= 4√3 / 3
S) Sin(60°) = x / (10/3)
x = (5√3) / 3
