Answer:
12
Step-by-step explanation:
Answer: 6√2m or 8.49.
Step-by-step explanation:
Drawing the right angled triangle and label the sides, AC, which is the hypotenuse and the longest, AB , one if the sides, and BC the third sides. Since it is an isosceles right angle triangle with the right angle at B, based on my own diagram here, two of the sides are equal.
AB = BC = 6m
Now to find the hypotenuse, we apply the Pythagoras theorem which states that the square of the sum of the two sides equal the square of the hypotenuse side.That is
AC² = AB² + BC²
AC² = 6² + 6²
= 36. + 36
= 72
AC² = 72, Therefore, AC which is the hypotenuse
AC = √72
= √36 × √2
= 6√2m. or 8.49m
Answer:
p = 92
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angle
p+45 = (p-47)+p
Combine like terms
p+45 = 2p-47
Subtract p from each side
p-p+45 = 2p-p-47
45 = p-47
Add 47 to each side
45+47 = p-47+47
92 = p
Use the order of operations or PEMDAS
For this case, the first thing we must do is define a variable.
We have then:
x: number of initial cards.
We write now the equation that represents the problem:
x - (4) * (6) = 54
From here, we clear the value of x:
x = (4) * (6) + 54
Rewriting:
x = 24 + 54
x = 78
Answer:
The number of cards that william has initially is 78. Lack of information to know how many cards his friends have.
