You answer will be X=0 hope this helps
An equilateral triangle has 3 congruent sides so the 2 expressions above are equal
3x - 9= 23 - 5x
And then you solve for x
-22=-2x
X=11
Answer:
135°
Step-by-step explanation:
∠AOB = ∠COB = 90°
∠BOK = 45°
90 + 45 = 135°
N=m-2
m-2n=8, using n from above in this equation yields:
m-2(m-2)=8 perform indicated multiplication
m-2m+4=8 combine like terms on left side
-m+4=8 subtract 4 from both sides
-m=4 divide both sides by -1
m=-4
So the correct answer is A) m=-4
