Answer: b) 2 units left, 4 units up, reflect across y-axis
<u>Step-by-step explanation:</u>
The easiest way to do this is to graph the black triangle using the the given options to see which one lands on the red triangle.
The second option is the one that works.
Answer:
Step-by-step explanation:
Formula for area of a triangle:
Height x Base /2
Base (b) = h +4
Height = h
h + 4 x h /2 = 30cm
=> h +4 x h = 60
=> h+4h =60
=> 5h = 60
=> h = 12
Height = 12
Base = 12 +4 = 16
So... hmmm if you check the first picture below, for 2)
we could use the proportions of those small, medium and large similar triangles like

now.. for 3) will be the second picture below
