Answer:
a = 40 degrees and b = 50 degrees
Explanation:
I don't remember the theorem but 40 degree from the outside is the same as 'a'.
a = 40 degrees
We will use the triangular theorem which is a + b + c = 180 degrees to help us get b. The angle c is 90 degrees because it has the square thing.
40 + 90 + b = 180
130 + b = 180
130 - 130 + b = 180 - 130
b = 50 degrees
If you don't understand this... try the picture. I put more effort for it.
Its because your profile picture is my childhood show! Hello Kitty! <3
I hope this helps and I very so sorry for not remembering the theorems.
I used touch pad while drawing this and drawing numbers are hard for me.
