In a right triangle, the hypotenuse is always the longest side. Plus, the hypotenuse squared has to equal the sum of the squares of the other 2 sides. For the first "triangle" above: does
? Let's check. 196 = 25 + 16 so does 196 = 41? Obviously not. So that is not a right triangle. Let's check the second one the same way. Does
? 25 = 9 + 16. Does 25 = 25? Of course it does! So 1 is not a right triangle, but 2 is!
Solution:
we have been asked to find
The smallest value of n such that the LCM of n and 15 is 45.
The prime factors of 15 are
So in LCM of n and 15 , we must include both the prime factors and the LCM is 45.
Since 3 is one time in the prime factor of 15. But to make 45 we need one more 3 and its possible if we take the value of n as below"
n=9
Hence the LCM will be
Hence the smallest possible value of n is 9.
Answer:
220 degree
Step-by-step explanation:
Given the radius=18cm , pi=3.14.. , area=198π
Area of a sector =∅×π×r²/360
or,198π=Θ×π×r²/360
or,Θ=360×198π/πr²
∴Θ=220°
The answer is 7 meters.
Area is (pi)r^2
If we remove pi, we have 49=r^2
This means that r=7
