11.d is a point on the side of triangle abc, such that angleadc=anglebac. show that ca^2=cb. cd

Question is Incomplete,Complete Question is below.

D is a point on the side BC of a triangle ABC such that angle ADC = angle BAC Show that CA square=CB .CD

The Proof is given below.

Step-by-step explanation:

Given:

In ΔABC,

∠ADC = ∠BAC

To Show:

Proof:

In ΔBAC and ΔADC

∠ADC = ∠BAC ............................Given

∠C = ∠C .....................................Reflexive Property

∴ ΔBAC ~ ΔADC .................... A-A similarity test

If two triangles are similar then their sides are in proportion.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
