Find the area of a triangle when a=40, b=14, c=9
a. 18.5
b. 40.5
c. 27.9
d.26.3

b. 40.5

Step-by-step explanation:

The appropriate formula for the area is ...

area = (1/2)bc·sin(A) = 63·sin(40°) ≈ 40.5 . . . . square units

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
