Answer:
It is a right triangle.
Step-by-step explanation:
By the Inverse Pythagoras Theorem if 39^2 = 36^2 + 15^2 then it is a right triangle.
39^2 = 1521
36^2 + 15^2 = 1296 + 225 = 1521.
So it is a right triangle.
Answer:
m = 5
Step-by-step explanation:
We are told that the two triangles are similar. Thus, each side of the larger triangle is the same multiple of the corresponding side in the smaller triangle.
Thus, 12 = k(7.2), where k is the constant of proportionality.
Solving this for k, we get
k = 12/7.2 = 1 2/3
Thus, side m is 1 2/3 times 3, or 5/3 times 3, or just 5.
m = 5
<span>In this item, it is unclear of the weights of each of the
t-shirt and sweatshirt. We first represent the weights of the t-shirts and the
sweatshirts by t and s, respectively. If for example, each t-shirt weighs 2
pounds and each sweatshirt weighs 3 pounds, the answer would be the first
choice. </span>
