Answer:

\frac{-6}{7}

Step-by-step explanation:

Let the other number be 'x'

x + \frac{-15}{7} = -3

         x = -3 +  \frac{15}{7}

           = \frac{-3*7}{1*7} +\frac{15}{7}\\\\=\frac{-21}{7}+\frac{15}{7}\\\\= \frac{-21+15}{7}\\\\= \frac{-6}{7}

Sum = -3

First no. = -15/7

Second no. = (-3) - (-15/7)

= -3 + 15/7

= -21/7 + 15/7

= (-21 + 15)/7

= -6/7

The second no. is -6/7.

The hypotenuse of a 45°-45°-90° triangle measures 128 cm. A right triangle is shown. The length of the hypotenuse is 128 centime
Aleks [24]

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
