Answer:
1) b=14.34 units.
2) a=20.48 units
Step-by-step explanation:
since, the triangle is a right angled triangle so we can use the trignometric identity in order to find the values of a and b.
let the base be denoted by 'B'.
height or perpendicular side of the triangle be denoted by 'P'.
and hypotenuse of the triangle be denoted by 'H'.
then using sine and cosine trignometric identity we have:
and
Here x=35°
and H=25 units , P=b and B=a
Hence
as
hence, b=14.3394 units.
also
and
Hence a=20.4788 units
In two decimal places we could represent it as:
a=20.48 units
and b=14.34 units.
