Find the measure of the exterior angle

133°

Step-by-step explanation:

Exterior Angle Theorem states that the sum of the two remote interior angles is equal to the exterior angle of the triangle.

Step 1: Combine like terms.

Step 2: Subtract x from both sides.

Step 3: Subtract 13 from both sides.

Step 4: Divide both sides by 2.

Step 5: Plug in 40 in 3x + 13.

Therefore, the answer is 133°.

step-by-step explanation:

abc

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
