An isosceles trapezoid has base angles of 45° and bases of lengths 9 and 15. the area of the trapezoid is 36 sq. units 67.5 sq. units 72 sq. units

36 sq. units

Step-by-step explanation:

Area of any Trapezoid can be found by the formula Area=

The base angles are given as 45 degrees so we have a 45 45 90 triangle .In 45 45 90 triangle legs are same so height = 3.

Area of trapezoid =

                            =

20

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
