What is the radius and diameter of the following circle 16cm

In the figure below, segment ac is congruent to segment ab: triangle abc with a segment joining vertex a to point d on side bc. side ab is congruent to side ac which statement is used to prove that angle abd is congruent to angle acd? segment ad bisects angle cab. triangle acd is similar to triangle abd. segment ad is congruent to segment ac. angle cab is congruent to angle cba.

Find the vertex of the function given below y=x^2-6x+1

In parallelogram abcd the ratio of ab to bcis 5: 3. if the perimeter of abcd is 32 find ab
