Answer:

Length of each leg = 8.91 units

Length of each angle other than right angle is 45°

Step-by-step explanation:

For better understanding of the solution see the attached figure :

ΔABC is right angled isosceles triangle ⇒ AB = BC

Now, by using Pythagoras theorem :

AC² = AB² + BC²

12.6² = 2×AB²

AB² = 79.38

AB = 8.91 units

So, BC = 8.91 units

Now, Since AB = AC

⇒ ∠BAC = ∠ACB ( equal sides have equal angles opposite to them)

Now, By using angle sum property of a triangle

∠ABC + ∠BAC + ∠ACB = 180°

90° + 2∠BAC = 180°

2∠BAC = 90°

∠BAC = 45°

⇒ ∠ACB = 45°

velikii [3]

Answer:

dy/dx at x=6 is 0.334

Step-by-step explanation:

The center difference method requires that the values of the function are given in equal intervals which is the case, and allows one to find the value for x = 6 using those of the function for x = 5.5 and for x = 6.5 as follows:

\frac{dy}{dx} =\frac{3.7436-3.4096}{6.5-5.5} =0.334

Ostrovityanka [42]

Answer:

8 units.

Step-by-step explanation:

The smaller of the right triangles formed is similar to the whole triangle so

4/x = x/16   where  x = the shorter leg

x^2 = 64

x = 8.
