3. in a triangle, two angles have measures of 45°
and 85°. what is the measure of the third angle in
this triangle?

50 degrees

Step-by-step explanation:

let angle be x

45 + 85 + x = 180  (angle sum property)

x=180-130

x=50 degrees

3rd angle=x=50 degrees

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.
