Answer:
We just multiply 75 with 3 to make it a perfect square. This is because, 75 = 5 × 5 × 3. 3 doesn't have a pair. Thus 75 × 3 = 225 and √225 is 15.

Answer:
Pretty sure its 4/5
Step-by-step explanation:
Ratio is 20:25 simply it by dividing 5 its 4:5 then as a fraction it's 4/5
The answer is 1 + 4 = 5 + 4= 9 + 4 = 13 + 4 = 17 + 4 = 21 + 4 = 25
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
the answer is 90
