Diagram shows a cone and its axis of rotation which type of cross-section is formed when the cone is intersected by a plane cont

MAXImum [283]

Answer:

The cross section will be an isosceles triangle

Step-by-step explanation:

The picture of the question in the attached figure N 1

we know that

If a plane passes through the axis of rotation of the cone, then the resultant cross-section will be a triangle with one vertex as the vertex of the cone and the two sides of the triangle through the vertex A will be equal.

Where the base of the triangle will be equal to the diameter of the circular base of cone and the two congruent sides of triangle will be equal to the slant height of the cone

therefore

The cross section will be an isosceles triangle

Can someone help me with 1& 2 will mark brainiest

melamori03 [73]

Sin 45° = opposite side / hypotenuse

1/2 = 8/h
h = 16

2)6/12 = 1/2
1/2 = sin 45°

6√3/12 = √3/2
√3/2 = cos 30°

Sum of angles of triangle = 180°
The 3rd angle = 180 - (45 + 30) = 180 - 75 = 105°

Angles = 30° , 45° , 105°
