Áp dụng định lí pytago trong \(\Delta MNP\) vuông tại \(M\) có:

\(\Rightarrow MP=\sqrt{NP^2-MN^2}=\sqrt{7,5^2-4,5^2}=6cm\)

\(\Rightarrow D\)

Chọn D nhé bạn

My school is on the small street of a bustling city. The quiet day passed with the teacher's lectures and the naughty games of the pupils "most demon, second ghost ...". I also do not care about the concept of "library" do nothing if there is a problem in the final exam of the whole class I mostly underestimated. If the topic is as always, then we do not need to read the book we all students, because the answer is already in the notebook, so that the same. In this article, the article expanded, asking students to really find it hard, refer to more documents related to that problem to meet the requirements. We were all over when we read the card. The teacher also instructed us to go to the school library to read more books, but none of them paid attention. After a poorly remembered life, we were aware of the importance of reading and learning, but how did we start when we did not have a destination that really inspired passionate students? love to fly, like new and dynamic.

A good library is an ocean of information, whose boundaries continue to extend with the endless contribution of the numerous streams of knowledge. Thus, it has a peculear fascination for scholars, and all those whose thirst fo knowledge is instable.
