Every triangle has 180 degrees when you add there angles so you know that they will add up to 180
they are right triangles so the right angle has 90 degrees
so for the yellow triangle
90+45+x=180
135+x=180
45=x
we can tell where the purple and yellow triangle touch is 90 so 45+x=90 to find that angle which is 45
and the other one is 45
so there are two 90 degree angles and three 45 degree angles.
I hope that made sence

1, 3, and 5 because you can multiply all these numbers to get 15
I would say it would be 55 and if this question.If you get the answer incorrect my apologies
Step-by-step explanation:
40 + y + y + 30 = 180
2y + 70 = 180
2y + 70 (-70) = 180 (-70)
2y = 180 - 70
2y = 1102y/2 = 110/2
y = 110/2
y = 55
