Answer:
21°
Step-by-step explanation:
we know that every single triangle has to equal 180°
we have all 3 angles 90° 34° 35° which equal 159°
so we take 180°-159° and your answer is 21°

Answer:
P(yellow or red)   =8/15
Step-by-step explanation:
There are 15 marbles, 3 green, 4 blue, and 5 red marbles.
3+4+5 = 12
That means there are 15-12 = 3  3 yellow marbles.
3 green, 
4 blue
 5 red 
3 yellow
To find the probability of yellow or red, we add the number of yellow and red marbles together over the total number of marbles
P(yellow or red) = (yellow +red)/ total
                            = (3+5)/ 15
                              =8/15
