A triangle has side lengths of 14, 23, and 27. Is it a right angle ?
shusha [124]

Answer:

No, it is not

Step-by-step explanation:

Here, we want to check if the lenghts given is that of a right angle triangle

For a right angle triangle, the square of the hypotenuse is equal to the sum of the squares of the two other sides

The hypotenuse represents the longest side

So 27^2 = 14^2 + 23^2

The difference between these is 4, and as such the triangle is not a right angled

Please I need help with this Question
frutty [35]

Answer:

The data set with the greater range is the Girls

The greater median is the Girls at 110

Step-by-step explanation:

The range is the difference between the largest and smallest values.

As the largest value for the boys is 120 and the smallest is 60, the range would be 60

As the largest value for the girls is 150 and the smallest is 70, the range would be 80.

This means that the Girls have the greater range

The median is the number in the middle when the data is in ascending order.

As we have an even number, we will have to find the middle value between 5 and 6. To do this, we can add them together and divide them by 2.

The 5th boy in ascending order is 90 and the 6th boy is 90.

(90+90)/2=90

The 5th 5irl is 100 and the 6th girl is 120

(100+120)/2=110

This means that the median is greater for the Girls.
