Answer:
64√2 or 64 StartRoot 2 EndRoot
Step-by-step explanation:
A 45-45-90 traingle is a special traingle. Let's say one of the leg of the triangle is x. The other one is also x because of the isosocles triangle theorem. Therefore, using the pytagorean theorem, you find that x^2+x^2=c^2. 2(x)^2=c^2. You then square root both sides and get c= x√2.
Therefore, the two legs are x and the hypotenuse is x√2. x√2=128 because the question says that the hypotenuse is 128. Solve for x by dividing both sides by √2. X=128/√2. You rationalize it by multiplying the numberator and denominator of the fraction by √2. √2*√2= 2.
X=(128√2)/2= 64√2 cm.
Since X is the leg, the answer would be 64√2
There are 540 degrees total in the interior angles of a regular pentagon.
Just so you know, the total degrees of interior angles goes up by 180 degrees.
A triangle is 180 degrees, a quadrilateral 360, and a pentagon 540.
You can convert them to decimals and multiply. Remember when using decimals, it is over 10 or 100 <span />
Answer:

9*10^3=9000
1 kilogram = 2.2 pounds
45 kilograms = 2.2 x 45 = 99 pounds
