Answer:
x = 15
m∠1 = 45°
Step-by-step explanation:
2x + 15 + 135 = 180
2x = 180 - 15 - 135
2x = 30
x = 30/2
x = 15
180 - 135 = 45°
The area of a square is:
A=s^2, solve this for s
s=√A
The "diagonal" is the hypotenuse of a right triangle with legs of length s.
By the Pythagorean Theorem:
d=√(s^2+s^2)
d=√(2s^2), and since we found that s=√A earlier:
d=√(2A), and since we are told that A=128m^2
d=√256
d=16m
Answer:
5 ft : 3 ft
Step-by-step explanation:
Ratios are always fractions so we can turn this to a fraction; 
Then to reduce to it's lowest terms divide by a number that can divide both of them. Lets divide by 2 since it can divide the two numbers
We can still divide by 2 since it can divide both numbers = 
Since no number can divide both of them at the same time the answer is OR 5 ft : 3 ft
