Ответ:
NMO = 59
Step-by-step explanation:
If MO bisects LMN then LMO equals OMN
LMN = LMO+OMN
Since LMO = OMN
LMN = LMO + LMO
LMN = 2 LMO
Substituting LMN = 5x-22 and LMO = x+31
5x - 22 = 2( x+31)
Distribute
5x-22 = 2x+62
Subtract 2x from each side
5x-2x-22 = 2x-2x+62
3x-22 = 62
Add 22 to each side
3x-22+22 =62+22
3x = 84
Divide by 3
3x/3 = 84/3
x =28
LMO = x+31
=28+31
=59
NMO = LMO
NMO = 59
Ответ:
If MO bisects ∠LMN then m∠LMO = m∠NMO
and m∠LMN = m∠LMO + m∠NMO
Therefore m∠LMN = 2 · m∠LMO
We have m∠LMN = 5x - 22 and m∠LMO = x + 31. Substitute:
5x - 22 = 2(x + 31) use distributive property a(b + c) = ab + ac
5x - 22 = (2)(x) + (2)(31)
5x - 22 = 2x + 62 add 22 to both sides
5x = 2x + 84 subtract 2x from both sides
3x = 84 divide both sides by 3
x = 28
m∠NMO = m∠LMO = x + 31
Put the value of x:
m∠NMO = 28 + 31 = 59
m∠NMO = 59°Ответ:
y=3x+(-1)

Whenever I have questions like these, I use desmos. I put the points I'm given into the calculator (separately), and to find the line, it's just trial and error from there! Have a lovely day :)
