Answer:
175lb
Step-by-step explanation:
Let's say 100% - original weight
and 12% - 21lb
weight = (100*21)/12=175lb
A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. They lie above the main sequence (luminosity class V in the Yerkes spectral classification) on the Hertzsprung–Russell diagram and correspond to luminosity classes II and III.
where A is area
a is side a lets say its 8cm
b is side b lets say its 7 cm
theta is 28
Slope = rise/run = 10/50 = 1/5
Any
in this set will be real numbers that are both less than
and greater than
. But that's not possible, so this set is empty.
