Can someone plzzz help me with this one problem!

2?

Step-by-step explanation:

i think its 2 because 1 is an odd number and it goes 1,1 ( two odd numbers) then __ 3,5 ( two more odd numbers then 8,13,21( even number then two more odd numbers) the 34( even number). i'm thinking the pattern is odd, odd, even, odd, odd, even, odd odd, even.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
