For the answer to the question above, you see that the sides AD and CD are congruent, therefore opposite angles A and C are congruent.
<span>if you want to prove that two triangles are congruent by SAS, you have to show that two corresponding sides are congruent and that the angle between those corresponding sides is congruent also. </span><span>once you do that, the triangles are proven congruent by SAS</span>
Ask your teacher not us. thanks management. :)
The first one is 5c√10c/3d^3
The answer is: A, 5c√10c/3d^3
Hope this helps! :)
it would be 99 millimeters think. 10,000/100 is 100 so .99 x 100 is 99.
