A place for my thoughts. Maybe yours. Maybe we can talk. It's up to you and whether or not you post here.
Just don't be a jerk.
Can someone explain me how do you calculate this?
The opposite angles made by 2 intersecting lines must be equal, so we know that m/3 + 75 = m/2 + 64.
From there we can solve it like any equation
m/3 + 75 = m/2 + 64
-m/3 -m/3
75 = m/6 + 64
-64 -64
11 = m/6
×6 ×6
66 = m
One of the angle things with two straight intersecting lines means the two angles are equal, from there its just algebra.
Take 64 from both sides, take m/3 from both sides. Times both sides by 6, m=something, idk i didnt do the actual math.
well question marks, as far as I know, are a way of asking a question.
Well, we know that BA and DC are lines connecting points and therefor they are straight, that means opposite angles are equal.
m/3 + 75 = m/2 + 64
We don't like those fractions we're gonna get rid of them, Lowest Common Denominator is 6
6(m/3 + 75) = 6(m/2 + 64)
6(m/3) + 6(75) = 6(m/2) + 6(64)
2m + 450 = 3m + 384
Now separate the variables to one side and numbers to the other
2m - 2m + 450 = 3m - 2m + 384
450 = m + 384
450 - 384 = m + 384 - 384
66 = m
Let's test that out by plugging it back into the original equation
66/3 + 75 = 66/2 + 64
22 + 75 = 33 + 64
97 = 97
Seems legit
m = 66
But why m? I think that's m as in "y=mx+b" or the slope of the line? Kind of a weird notation but honestly just ignore it. It's just a regular variable for now.
