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°
Check the picture below.
so, that'd be 20.24845673131658693325, and to the nearest tenth it'd then be 20.2
Answer:
Step-by-step explanation:
if anna is x years old and her sister is 5 five years older the eqasion would be x=5-5x but there is no further information for the answer. You need to know how old anna is to answer the question. Did you write it correctly
= -2? i dont really know either
Think about it this way, that for every 5/6 pound bag you are losing 1/6 and 1/6*12=2 therefore the answer is 12
