35 + 55 = 90

Well all triangles equal 180 so add up the angles you know and subtract it from 180 and you'll get the answer I think
1. 196 to 7=28.14
2.65 out of 105=1.61
3.112:140=0.8
4. 0.11 to 1.21=11
5. 19:76=0.25
6. 18 to 27=0.66
5 + 4x
I think that’s right
Answer:
3x^2-6x+3=0
x^2-2x+1=0
x^2-x-x+1=0
x(x-1)-(x-1)=0
(x-1)(x-1)=0
x=1,1
so x has only one answer
so it intersects only one time
