At an argheological site, the remains of two ancient step pyramids are congruent. If ABCD=EFGH, find m/_EHG.

m∠EHG = 68

Step-by-step explanation:

If the two ancient step pyramids are congruent,

ABCD ≅ EFGH

All the angles and sides of the two pyramids will be congruent.

By the property of congruence,

Base angles of both the pyramids will be congruent.

m∠ADC = m∠EHG = 68°

Therefore, m∠EHG = 68 will be the answer.

c. the third graph

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
