Find x. round to the nearest tenth.

21.4 degrees =x

Step-by-step explanation:

We can use the law of sines to solve this problem

sin A            Sin B

=

a                  b

where A is the angle and a is the opposite side

sin 42           Sin x

=

22                  12

Using cross products

12 sin 42 = 22 sin x

Divide by 22

12/22 sin 42 = 22/22 sin x

12/22 sin 42 =  sin x

Take the arcsin of each side

arcsin (12/22 sin 42) = arcsin( sin x)

arcsin (12/22 sin 42) =  x

21.40637223=x

Rounding to the nearest tenth

21.4 degrees =x

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
