a,b,c are the sides.
1) first idea
Theorem of Al' Kashi (genralized pythagorean theorem) will help us
a²=b²+c²-2bc cosA ==>49=49+25-2*7*5*cos A
==>cos A=25/70=5/14 ==>
A=69,075167572361683699967605141899 °≈69°
b²=a²+c²-2ac cos B ==> 49=49+25-2*7*5 * cos B==>cos B=5/14
B=A (triangle is isocele ==> a second method)
C=180-2*69=42°
II)
The triangle isocele is formed with 2 right triangles.
(base=5/2 hypotenuse=7)
cos B=(5/2)/7=5/14 (the same) ==>B=69°
A=B=69°
C=42°

The probability of drawing a yellow marble is
Since he replaces the marble after it is drawn out, the probability of drawing another yellow is the same:
The probability of drawing a red marble is
In order to get the probability of drawing 2 yellow marbles and 1 red marble, given that each marble is replaced after it is drawn out, we must multiply the fractions together.
Because the order of the marbles doesn't matter, we will multiply the probability by 3.
