Answer 1

Step-by-step explanation:

Step-by-step explanation:

wer:

According to ASA criterion , If two angles and their included side in one triangle are equal to the two angles and their included side in other triangle, then the triangles are congruent.

So, if side AT=PN in the given two triangles.

The triangles are congruent if,

∠RAT=∠EPNA box contains 20 cards marked with numbers I to 20. One card is drawn at

random Wnte the event A using the nurmber on the card is a multiple of 4. Write

S, nS). A and n(A)

∠ATR=∠PNE

Answer 2

Let the height of cone be 'h', thenπr 2 H= 31 πr 2 h=4400㎤⇒πr 2 [21− 3h ]=4400⇒63−h= 22×10×103×4400×7 =42⇒h=63−42=21㎝
