Nolan drew a right triangle. how many acute angles did he drew?

vagabundo [1.1K]

2 acute angles because all of the angles of the triangle must add up to 180 degrees. If you used 90 degrees already you only have 90 degrees left to make the other two angles.

A piñata is a container filled with candy and is broke by hitting it with a stick. The probability that Amanda will break a piña

Jet001 [13]

Answer:

0.3024

Step-by-step explanation:

Given the following :

Probability of breaking pinata on first hit = 0.58;

P(first hit break) = 0.58

P(does not break on first hit) = 1 - p(first hit break) = 1 - 0.58 = 0.42

P(2nd hit break) = p(first hit break) + 0.14 = 0.58 + 0.14 = 0.72

Hence, Calculate the probability that Amanda does not break the piñata on the first hit and does break the piñata on the second hit

P(does not break on first hit) * p(2nd hit break)

0.42 * 0.72 = 0.3024
