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
It is given in the question that
If four angles of a convex pentagon measure 120°, 93°, 108°, and 101°, find the measure of the fifth angle.
First we have to find the sum of measurement of all the angles of a convex pentagon, by using the formula
Where n is the number of sides. And for polygon, it is 5 .SO the sum of measurement of angles of a polygon is
Let the measurement of missing angle be x .
So we have
