Answer:
let the equal sides of the triangle be of length "a" . let the angle between these two sides be " x ". Then drop a perpendicular from the vertex to the base. now u have 2 similar triangles .the angle between the perpendicular and one of the equal sides is now (x/2) . length of perpendicular = a cos(x/2) length of base = 2a sin(x/2) . area of triangle = (1/2) 2sin(x/2) cos(x/2) a-square
= (1/2) (sin x) a-square

Answer:
\simeq 14.94 billion dollars
Step-by-step explanation:
During the period 1994 - 2004, the 'National Income' ,(NI) of Australia grew about 5.2% per year (measured in 2003 U. S, dollars). In 1994 , the NI of Australia was $ 4 billion.
Now,
(2020 - 1994) = 26
Assuming this rate of growth continues, the NI of Australia in the year 2020 (in billion dollars) will be,
=
=\simeq 14.94 billion dollars (answer)
