Again, this is a triangle so the sum of the angles must be 180°, so we can say:
a+b+c=180, we are told a=129, b=2c, we will let c=M°
129+2c+c=180 combine like terms on left side
129+3c=180 subtract 129 from both sides
3c=51 divide both sides by 3
c=17°
So angle M=17°
Answer:
No
Step-by-step explanation:
These are linear equations (y=mx+b). Your slope or m for both equations is 5 and linear equations with the same slope are parallel. Which means they will never cross so they will never have the same amount of tiles.
I got 70
Combination=n!/((n-r)!r!)
=8!/((8-4)!*4!)
=8*7*6*5*4!/(4!*4!)
=8*7*6*5/(4*3*2)
=70 ways
