Answer:
∠c = 33°
∠b= 147°
Step-by-step explanation:
A line is 180°, and ∠c + 147° make up a linear pair.

∠b = 147°.
Answer:
A 100 lb person will weight 40 lb on Mars
Step-by-step explanation:
Given:
Weight on Mars directly varies as its weight on earth.
Let weight on Mars be = 
Let weight on Earth be =

∝ 
Thus
where
is constant of proportionality.
when
, then 
thus, we have
dividing both sides by 95.
∴ 
Thus when
,
would be calculated as


∴
(Answer)
∴ A 100 lb person will weight 40 lb on Mars.
