Hello!
Since the second triangle is larger than the first this is an enlargement
To find the scale factor you find what the angles were multiplied by
(0 , 1) * 3 = (0 , 3)
(-1, -1) * 3 = (-3, -3)
(1, -1) * 3 = (3, -3)
So the scale factor is 3 since the coordinates were multiplied by 3
Hope this helps!
Answer:
29.12%
Step-by-step explanation:
Given that :
A = 49
B = 50
C = 38
D = 60
E = 75
Total = (49 + 50 + 38 + 60 + 75) = 272
Pie chart % for each :
A = (49 / 272) * 360 = 64.85
B = (50 / 272) * 360 = 66.18
C = (38 / 272) * 360 = 50.29
D = (60 / 272) * 360 = 79.41
E = (75 / 272) * 360 = 99.26
Difference between C and D
(79.41 - 50.29) = 29.12%
The answer to this is 81x^2.
With area, you multiple two sides. With a square, all sides are equal and so, you just take 9x and multiply it by 9x.
9 x 9= 81
X x X= X^2
And so, the answer is 81x^2
Area of triangle = 0.5 * base * height
30 = 0.5 * 6 * base
30 = 3 * base
so , base = 10 inch
