Answer:
1(d), 2(not correct) 3,4,5 given below
Step-by-step explanation:
1. the slopes are same as we know
m=tan theta=y/x so the slope is same
2. it will be 10 m= tan theta=y/x
or, slope =70-40/7-4=10
3. let x and y are the sides of the triangles
so for 1 triangle it will be x=5 and y=2
"" "" another one its the multiple of 5 and 2 such as x=10 and y=4
4. the two triangle lie on the same line as slopes are equal
1st one , slope=72/12=6
2nd one slope=144/24=6
as slopes equal so they are collinear.
5. i am sorry i am not sure about it
i took all the three lines. as the slope of 5 and 7 no triangleare same(m=0.75) and smaller than others then on line A
then slope of 8 and 9 no triangle are same(m=1.5) so on the line B
then slope of 6 and 10 are same (m=3) so on the line C
i took the three lines for this...
THE ALL ANSWERS ARE BASED ON PRIMARY CONCEPT IF U FIND ANY MISTAKE PLEASE TELL ME LATER..THANK U
