Answer:</u></h2>
The point M is the midpoint of the line section PQ. Just a line fragment can have a midpoint. A line can't since it goes on uncertainly in the two bearings, thus has no midpoint. A beam can't on the grounds that it has just a single end, and henceforth no midpoint.
The Midpoint Formula works the very same way. In the event that you have to discover the point that is actually somewhere between two given focuses, simply normal the x-values and the y-values.
Answer: 644
(20x25)+(18x8)
(500) + (144)
=644
Answer: ∠DOB: 48°
Step-by-step explanation:
1. we need an equation first. the sum of all angles (108°, n°, 2n°) is equal to 180°. we can depict this with the equation: 108°+2n°+n°=180°
2. now we can solve for the missing variable, n.
108°+3n°=180° → subtract both sides by → 3n°=72° → divide both sides by 3 → n=24°
3. now that we know that n=24°, we can solve the value of ∠DOB. we can see that ∠DOB is 2n° which we just plug the number we got for n into the equation. 2*24=48° meaning ∠DOB is 48°
hope this heped! ♡
