When a perpendicular is dropped from the right-angle (C) to the opposite side AB, the metric relations apply:
BD*BA=a^2 ..........................(1)
AD*AB=b^2...........................(2)
BD*DA=DC^2........................(3)
Given AD=6, AB=24, using metric relation (2) above, we have
b^2=6*24=144
=>
b=sqrt(144)=12
By the way, we conclude that this is a 30-60-90 triangle because b/AB=(1/2)=sin(B) => B=30 degrees.
Answer: b=12
Answer:
10 students
Step-by-step explanation:
5250 + 4800 + 3990 + 5120
19160 / 4 = $4,790 average monthly income
Diameter = 10cm
radius =10/2 = 5 cm
Area = πr² = 3.14 * 5² = 78.5cm²
80 percent...... Ratios are the same as fractions so its just like 4/5
