The first one would reduce the size because it would now be 4/5 of the actual size
The scale factor 7/2 would enlarge it because it is getting 3 1/2 time larger than the oringanl size
Answer:
Since we know that ΔPQR is a right triangle, we can also asume that:
sin R = cos P = 3/5
So the answer is (d).
* This formular can also be applied to other right triangles.
In a right triangle, sine of one acute angle will always be equal to cosine of the other acute angle.
And we can check this by actually finding cos P using the lengths of the sides, by calculating PR first:
PR = √(PQ² + RQ²) = √(12² + 16²) = 20
=> cos P = PQ/PR = 12/20 = 3/5
Answer:
The linear relationship between the length of someone's femur and their expected height..
Multiples of 5 are: 5,10,15,20,25,30,35,40,45,.......
Multiples of 7 are: 7,14,21,28,35,42,49,63,......
So the least common number is these two sets is 35, which is <span>the least common multiple</span> of 5 and 7
Hope you got it
