Answer:
Cos theta = sin(90-theta)
so cos 71 = sin(90-71)
cos 71 = sin( 19)
Therefore the answer = sin(19) = 0.14987720966
Hope it helps
Answer:
DM = 12
Step-by-step explanation:
I'm not very good with explaining but since MB is 12, vertex to the centroid which is M is 2/3 of the median, which is the line. So, since 12 is the 2/3 of the median, then DM would also be 12, since it's from vertex to centroid. Hope this helped.
Composite.
Because the definition of them is, <span>A prime number has only two factors: 1 and itself. A composite number has more than two factors. The number 1 is neither prime nor composite. The prime numbers between 2 and 31 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 and 31 since each of these numbers has only two factors, itself and 1.
Hope this helped!!! :)

X+2.5 because you dont know her height of last year which would give you the variable X and this year she grew 2.5 inches which would make the equation X+2.5
