The hypotenuse leg theorem<span> which states that two right triangles are congruent if their hypotenuses are congruent and a corresponding leg is congruent. So, the missing information is PM=PN.</span>
Hi there!
Reduced means "to simplify".
66/42=1 4/7.
66÷6=11 and 42÷6=7.
Therefore, 11/7=1 4/7.
So, 66/42 reduced is 1 4/7.
Hoped I helped. :)
Okay 5 or more let it sore 4 or less let it rest. 550 the middle number is in the tens spot so look behind it, it's a 0. 0 is less than 4 so you round it down, but 0 is the lowest you can go so it stays 550. ANSWER: 550, stays the same
