Select all the correct answers. Based on these sets of side lengths, which triangles are right triangles?
8 units, 15 units, V75 units
08 units, 3 units, V73 units
16 units, 30 units, V50 units
5 units, 7 units, 174 units

08 units, 3 units, V73 units

Step-by-step explanation:

Pythagoras theorem can be used to determine which  sets of side lengths are for a right triangle

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

8² + 15² = √289

8² + 3² =  √73

16² + 30² =  √1156

only the second option is correct

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
