A triangle has one angle measure of 55 degrees and a second angle measuring 53 degrees. What is the third missing angle measure? degrees..

A triangle has a total degrees of 180, so you add 55 and 53 to get 108

then you subtract that from 180 to get 72. 72 is your answer

72 degrees

Step-by-step explanation:

First of all, you should know that each triangle equals to 180 degrees. So just add 55 + 53 which equals 108. Then you just subtract 108 from 180 (180-108) which equals to 72 degrees.

Therefore, the third missing angle measure is 72 degrees.

Hope this helps! :)

step-by-step explanation:

the answer would be 7

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
