For <span>12/15=47/50, we multiply 12/15 by (1/3)/(1/3) to get 4/5. For 47/50, we multiply it by (1/10)/(1/10) to get the same denominator and 4/7/5. They are not equal.
For 16/36 and 12/27, we'll notice that 36 and 27 are both multiples of 9, so we need to get that as the denominator! Multiply 16/36 by (1/4)/(1/4) because 9 goes into 36 4 times and 12/27 by (1/3)/(1/3) due to that 27 goes into 9 3 times, we get 4/9=4/9 - these are equal!
I challenge you to get the rest of them on your own using my techniques!</span>
A reflection I think is true
Answer:
The answer is option D.
Step-by-step explanation:
cos M = adjacent / hypotenuse
From the picture
b is the adjacent
x is the hypotenuse
so
cos M = b/x
Hope this helps you
Answer:
we need the question
Step-by-step explanation:
Angles in triangle add to 180 degrees
20x=180
x=9
Angle ABC is the top one
8x9=72
