Answer: C. 39 !!!!!!!!!!!
12/y=4/5 so 4y/5=12 so then 4y=60 and y=15
x/5=y/3 so x/5=15/3 so x/5=5 so x=25
Answer:
5
Step-by-step explanation:
Find the greatest common divisor:
gcd(20, 45, 15)
Find the divisors of each integer and select the largest element they have in common:
The divisors of 20 are:
1, 2, 4, 5, 10, 20
The divisors of 45 are:
1, 3, 5, 9, 15, 45
The divisors of 15 are:
1, 3, 5, 15
The largest number common to all divisor lists is 5:
divisors of 20: 1, 2, 4, 5, 10, 20
divisors of 45: 1, 3, 5, 9, 15, 45
divisors of 15: 1, 3, 5, 15
Answer: gcd(20, 45, 15) = 5
Answer:
It is not.
Step-by-step explanation:
For XY to be a tangent XY must be perpendicular to radius at point of contact with circle (X).
Perpendicular also means 90° angle between XY and radius.
90° angle means XYZ should be a right angled triangle
Test for right angle triangle: pythagoras theorem.
3.6²+2.7²≠1.8²
Hence not right angled. XY not a tangent.
