Answer:
ab = 1/2.
Step-by-step explanation:
The sides of the large square have length √5 while the sides of the small one have sides of length 2.
Each corner has a right triangle with legs of length a and b and hypotenuse 2.
So we have the system
a + b = √5
a^2 + b^2 = 2^2 = 4
Using the identity a^2 + b^2 = (a + b)^2 - 2ab:
4 = (√5)^2 - 2ab
4 = 5 - 2ab
2ab = 5 - 4 = 1
ab = 1/2.
Answer:
q6 : b=-22
Q7.60×4=3h. 240=3h. 80=3h
Step 1: Multiply both sides by 5.
4x = 2
5
(4x) * (5) = (2) * (5)
5
4x = 10
Step 2: Divide both sides by 4.
4x = 10
4 4
Answer:
x = 5

9^2 + 12^2 = 25^2
81 + 144 = 225
225 = 225
