Answer:
The chronological age is 30 years
Step-by-step explanation:
Q= (kM)/C
132= (22k)/ 25
3300= 22k
k= 150
Q= (150M)/C
100= (150 x 20)/C
100= 3000/C
100C= 3000
C= 30

Answer:
1.55 feet.
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle R = 24°
Hypothenus = RS = 3.8 feet
Opposite = ST = x
The value of x can be obtained by using the sine ratio. This is illustrated below:
Sine R = Opposite / Hypothenus
Sine 24 = x / 3.8
Cross multiply
x = 3.8 × Sine 24
x = 3.8 × 0.4067
x = 1.55 feet
Thus, the Lenght ST is 1.55 feet.
