For number 1, theat is not a right triangle as a squared plus b squared does not equal c squared
The answers to the questions
Answer:

Step-by-step explanation:
The probability that a randomly selected cap will not be green is equal to the number of non-green caps divided by the total number of caps.
Since there are 100 caps total and 22 are green, there must be
non-green caps.
Divide this by the total number of caps (100) to get the probability that a randomly selected cap will not be green:

Simplify by dividing both the numerator and denominator by 2:

okay so
117° + angle a = 180° (supplementary angle)
angle a = 180 - 117
= 63°
then angle a + angle b + 81° = 180° ( angle sum property)
so... 63° + angle b + 81° = 180
144 + angle b = 180°
angle b = 180 - 144
= 36°
hope this helps.
