PLS HELP Given the following diagram, find the required measures.
Given: l || m
m∠1=120
m∠3=40
m∠4=
120
50
140

Measure 4 is 140. since both 3 and 4 are supplementary angles, this means that 40 + 140 equals 180.

definition of a supplementary angle:
angles that when added together, equal 180.

Your answer would be ahere is how: perimeter is how long all the sides are. in a rectangle, there are two sets of parallel sides. so, to find this, we would to the following.(15x2)+(4x2)30+838if you have questions ask! and mark me brainliest! i really wanna level up : 3
