The figure below shows the cross section of the scale model of a roof of a house. What is the length of the height RS of the roof rounded to the nearest tenth? A. 5.6 inches B. 7.5 inches C. 10 inches D. 12 inches<< My answer is this right?
9/x = x/16 x^2 = 144 x = 12
Look at the figure below. What is the value of x rounded to the nearest tenth? A. 2 B. 2.4 C. 3 D. 8.5<<My answer is this right
6/x = x/12 x^2 = 72 x = 8.48 or 8.5
first one is correct x = 12 inch
awesome! :)
second one , check again
did I do the set up wrong... 6/x = x/12?
perfect now :)
noo wait a sec
RSQ ~ PRQ => SQ/RQ = RQ/PQ x/6 = 6/12 x = 36/12 x = 3
from there I cross multiplied to get x^2 = 72 and the sqrt of 72 is 8.48 or 8.5
ohhh okay, I see what I did
great :)
so the answer is 3 right, just to clarify?
correct ans=3
therez another easy way to do this
if u r familiar wid 'right triangle mean theorem' else, the way you're doing is good enough :)
okay, thanks again so much! U really helped!
and I am, im still trying to get the hang of it though :)
