This is a Pythagorean Problem. Use the formula
c ^2 = a^2 + b^2
Givens
a = 8 - 7 = 1 cm
b = 12 cm
c = ?
solution
c^2 = 1^2 + 12^2
c^2 = 1 + 144
c^2 = 145 Take the square root of both sides
√c^2 = √145
c = 12.04
c = 12.0 to 3 sig digs.
100 % minus 18 % is 82% or .82
So multiply the price by .82 to get the sale price
300(.82)= 246
12/3 is already an improper fraction.
But, 12/3 is simplified into 4.
Answer:
They are congruent and corresponding!

Answer:
x = 24
Step-by-step explanation:
(2x - 4) + (3x + 5) + (2x + 11) = 180°
Combine like terms:
7x + 12 = 180
Subtract 12 on both sides:
7x = 168
Divide 7 on both sides:
x = 24
