so for this you need to know the thesis of the height of a right triangle so you have learned it in your schoole ?

4. LaynaMae

yeah i think so lol .. i'd have to look in my notes . but this is the 2nd to the last question i need to answer then i can log off of my school .... i dont wanna do all that lol

so what said that the lenght of the height from the right angle on the opposite side squared will be equal with the product of the lenghts of shadows of this height on hypothenuse sorry for my english but hope so much that you will can understanding right

6. jhonyy9

than PS=7 than RS^2 =PS*SQ ok ?

7. LaynaMae

oh wait lol i forgot to post the answers i have to choose from ! lol a.) 9.5 inches b.)16.1inches c.) 16.5 inches d.) 45.5 inches

8. jhonyy9

so than will be RS^2 =7*13 =91 than RS=sqrt91 = 9,5 inches so a), will be right ok ?
