Answer:
m∡A = 41.4°
m∡B = 48.6°
m∡C = 90°
a = 3
b = 9
c = 12
Step-by-step explanation:
to find the length of side 'a' I used the Pythagorean Theorem to get:
a² + 9² = 12²
a² + 81 = 144
a² = 63
a =
which equals 
which is 3
to find m∡B I found the arcsin(B) = 9/12 to get 48.6
to find m∡A I subtracted the sum of 90 + 48.6 from 180°
If a number can be written or can be converted to p/q form, where p and q are integers and q is a non-zero number, then it is said to be rational and if it cannot be written in this form, then it is irrational.
T(4,-1) means move 4 units to the right and 1 unit down.
Based on the image, M(-3,4) ; N(-2,1) ; P(-4,2)
So,
M:
-3 move 4 units to the right becomes 1
4 move 1 unit down becomes 3
M'(1,3)
N
-2 move 4 units to the right becomes 2
1 move 1 unit down becomes 0
N"(2,0)
P
-4 move 4 units to the right becomes 0
2 move 1 unit down becomes 1
P''(0,1)
Answer:
The answer to your question is Area = 49n² - 70n + 25
Step-by-step explanation:
Data
Length of the side = 7n - 5
Formula
Area of a square = side x side
Process
1.- Substitute values
Area = (7n - 5)(7n - 5)
2.- Expand
Area = 49n² - 35n - 35n + 25
3.- Simplify
Area = 49n² - 70n + 25
4.- The polynomial is 49n² - 70n + 25
