(b) one dihedral angle in methyl formate relates the plane containing the o=c–o bonds to the plane containing the c–o–c bonds. identify two structures of methyl formate: one in which this dihedral angle is 0° and the other in which it is 180°.

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

no solution exists the way you wrote the equation.
