Answer:
never
Step-by-step explanation:
let k be the scale ratio of two bodies then according to the question
k = a/b -- (1)
let Sa be the surface area of body A and Sb be the surface area of body B , then
according to the relation of scale factor and surface areas
from the above equation ,
as k = a/b from (1)
therefore
hence the ratio of their surface area is 
Well I’m guessing it went down by 20% to get to thirty pounds so
30 x 1.2 = $36 original price
Or if it’s lowered by 20% then
30 x 0.8 = $24
Hey there!
All of the angles of a triangle add up to 180. We already have 65+79 which is 144. This means only need 36 more degrees to get to 180.
Therefore, your answer is A) 36°.
I hope this helps!
