The shape of the cross-section formed is a triangle, when a cone is cut in such a way that the cross-section is perpendicular to the base and it passes through the vertex.
Ans should be 133°
Step-by-step explanation:
As we know..
sum of internal angles of a hexagon is 720°
So,
120+130+150+97+90+x=720
solving this we obtain value of x as 133°
Y = 0.5x + 3 is the equation
