Ответ:
EH = 9.4
Step-by-step explanation:
A rhombus is a quadrilateral with equal length of sides.
Given that, EF = 13 and DF = 18
⇒ DH = HF =
= 9
The property that the diagonals of a rhombus are at right angle to each other.
Thus, applying the Pythagoras theorem, we have;
= +
= +
= +
169 = + 81
= 169 - 81
= 88
EH =
= 9.381
The length EH is 9.4
Ответ:
It will be 2 feet and 9.6 inches wide
Step-by-step explanation:
First you divide 24 inches(2 feet) by 5 inches to find out the rate unit rate of change. Your answer would be 4.8. Then you multiply 4.8 by 7 to figure out how wide it would be, which gives you 33.6 inches(or 2 feet and 9.6 inches)
