Since we know that these two are consecutive angles and consecutive angles add up to 180 deg, we can come up with the equation 4x +5x =180. Solving this out shows us that x = 20 and the measure of angle J is 100 deg while the measure of angle M is 80 deg.
Answer: 530.66 units²
<u>Step-by-step explanation:</u>

The first two are alike because you have to add 3 to each side for everything to come out even.
Actually, no they cannot. The midpoint is the single point at the very center of the line segment. Since no segment can have multiple centers, they cannot have more than a single midpoint. Sorry :3
Hope this helped!! :D
Omg sorry i don’t really know i hope someone answers your question
