The measure of two vertically opposite angles are 140° and (x+40)°respectively. find the value of x.

x = 100

Step-by-step explanation:

vertically opposite angles are congruent, hence

x + 40 = 140 ( subtract 40 from both sides )

x = 100

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
