The leg of a right triangle is 4 units and the hypotenuse is 9 units. What is the length, in units, of the other leg of the triangle?
A. Square root 97 units
B. 97 units
C. Square root 65 units
D. 65 units

Length of the other leg of the triangle is √65 units

Step-by-step explanation:

Hypotenuse² = One side² + Other side²

9² = 4² + Other leg²

Length of the other leg² = 81 - 16 = 65

⇒ Length of the other leg of the triangle = √65

b) 36

step-by-step explanation:

18 times 2 is 36

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
