If the measures of two opposite angles of an isosceles trapezoids are 2x + 20 and 3x, what is the value of x?

x = 32

Step-by-step explanation:

An isosceles trapezium is one in which non-parallel sides have equal measure.

For an isosceles trapezoid, it is a rule that the two opposite angles equal 180°

∴ 2x + 20  3x = 180

solving the above equation:

2x + 3x = 180 - 20

5x = 160

x = 160 ÷ 5

x = 32

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
