What is the area of the triangle

40 square units

Step-by-step explanation:

Its a Right triangle, so you can use either of the legs of the right angle as the base and the height interchangeably.

Flip it over in your mind Area of a triangle is Hald of the base times height.

10 ×8 = 80  Divide by 2

80/2 = 40  units²

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

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
