Help me please only1,2and 4

1 answer:

No. 4:
Because the line BD bisects angle ABC, that means that both sides have the same angle.
So 6x=9x-27
-9x+6x=-27
-3x=-27
x=9

Now, you have to replace x in your angles.
So angle ABD is 54 degrees
6(9)=54

And
Angles DBC is 54 degrees too
9(9)-27
81-27=54

Do you know any of these three?

2. the ans is C because 3 sides in option C keep the same ratio as the 3 sides of triangle NOP: 7.5/5=1.5, 10.5/7=1.5 and 13.5/9=1.5

3. the ans is D
just see from the point Q(16,4), after the first dilation, the x-coordinate of Q=16*0.25=4, then by subtracting 4 from the x-coordinate of point T (i.e. -2-4=-6), then you can see only option D has the x-coordinate (x-6), so it shows that it is the ans

4. i dont know about this.. sorry :(
