4 0

The ratios 3:8 and 4:7 are not proportion. You can tell this easily by how in the second ratio, the first number is one larger, but the second number is 1 lower. If this was proportional, then both numbers would go either up or down depending on the circumstance.

The triangle is an isosceles triangle because of its degrees. A triangle consists of 180 degrees therefore, 180-90-45 simply makes it 45 matching the other side.

So we can assume that side b is also equivalent to side a. Here we use the pythagorean theorem to find x

a^2 + b^2 = c^2
5^2 + 5^2 = c^2
25+25=50

The square root of 50 is 7.1
x= 7.1

Nataly [62]

Answer:

Hence, player A will win with probability = 5/9. Explanation has given below.

Step-by-step explanation:

Two player such as A and B chose the three spinners and contain numbered 9 , 5 and 1.

Spinner one has 3 regions = (9, 5, 1)

Spinner 2 has three regions= (3, 8, 4)

Spinner 3 has three regions = (7, 6, 2)

Let

Player A chooses one of three spinners = (9, 5, 1)

Player B chose spinner = (3, 8, 4)

Possible outcomes are = [ (9,3), (9,8), (9,4), (5,3), (5,8), (5,4), (1,3), (1,8), (1,4)]

Total possible outcomes are = 9

One with the higher number wins the game.

Player A wins = (9,3), (9,8), (9,4), (5,3), (5, 4)

Player B wins = (5, 8), (1,3), (1,8), (1,4)

Hence, player A will win with probability = 5/9.
