Find the missing side. Round to the nearest tenth.

Step-by-step explanation:

1. have info for adjacent side and hypotenuse

so use; cosine

cos32=x/19

x=cos32×19

=15.9

2. have info for opposite side and hypotenuse

so use; sine

sin63=16/x

x=16/sin63

=95.6

3. have info for opposite side and adjacent side

so use; tangent

tan26=17/x

x=17/tan26

=14.4

4. have info for opposite side and adjacent side

so use tangent

tan42= x/13

x=tan42×13

x=29.8

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

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
