Pls help me on this !!!
Anuta_ua [19.1K]

Answer:

7, 12, 13

Step-by-step explanation:

Use the Pythagorean theorem equation on all of them. The one that does not make the equation true is the  answer.

a^2 + b^2 = c^2

A.

a^2 + b^2 = 18^2 + 80^2 = 6724

c^2 = 82^2 = 6724

Right triangle.

B.

a^2 + b^2 = 7^2 + 12^2 = 193

c^2 = 13^2 = 169

Not a right triangle.

C.

a^2 + b^2 = 3^2 + 4^2 = 25

c^2 = 5^2 = 25

Right triangle.

D.

a^2 + b^2 = 45^2 + 60^2 = 5625

c^2 = 75^2 = 5625

Right triangle.

Deirde spent 40% of her money in one shop and 35% of it in another. If she had €26.80 left, how much she at first​
Reil [10]

Answer:

107.20 euros.

Step-by-step explanation:

Let the amount she had initially be x euros.

Then we have the equation:

x - 0.40x - 0.35x =  26.80

x - 0.75x = 26.80

0.25x = 25.80

Multiply both sides by 4:-

x = 107.20 euros.
