Answer 2

Answer: Remember that subtracting a negative number is the same as adding a positive number.(two negatives equals a positive) For example:

35-(-55)=35+55

They are both equivalent. Now we can solve..

What is the length of side c, given a = 10, b = 8, and c = 105°? round the answer to the nearest tenth?

Answers

For this case, using the law of cosine we have:
c ^ 2 = a ^ 2 + b ^ 2 - 2 * a * b * cos (C)
Substituting values we have:
c ^ 2 = 10 ^ 2 + 8 ^ 2 - 2 * 10 * 8 * cos (105)
Clearing c we have:
c = root (10 ^ 2 + 8 ^ 2 - 2 * 10 * 8 * cos (105))
c = 14.33216827
round the answer to the nearest tenth:
c = 14.3
Answer:

In triangle TUV, Y is the centroid. If YW=30, what is TY?

Answers

Answer:

TY = 60

D is correct

Step-by-step explanation:

In triangle TUV, Y is the centroid.

As we know the centroid of the triangle is divides median into 1:2 ratio. The ratio is length of median from centroid to the side to length of median to opposite vertex.

Therefore, WY:TY = 1:2

$(WY)/(TY)=(1)/(2)$

where, WY=30

$(30)/(TY)=(1)/(2)$

$TY=2* 30$

$TY=60$

Hence, The length of TY is 60

TY=15 because the points bisect each other
