Answer:
1. 16 cm (squared)
3. 200 cm (squared)
Step-by-step explanation:
angles in a triangle need to equal 180 degrees
so x = 180 - 47 - 58
x = 180-105
x= 75 degrees
Firstly, we will select three corner points
A=(2,3)
B=(6,8)
C=(7,4)
we are given
the transformation with the rule (x, y)→(x, −y)
y--->-y
so, it is reflected about x-axis
so, we will multiply y-value by -1
we get new points as
A=(2,-3)
B=(6,-8)
C=(7,-4)
now, we can locate these points and draw graph
we get

They are a method for showing the frequency of a data plot in a much more compact and numerical way.
1[2 3
2[1 7
3[3 4 5 7
4[ 0 0 1
Key 1[2= 12
meaning that 3[5 is 35 and 4[0 is 40 and so and so forth
