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.
Answer:
5/3
Step-by-step explanation:
5/3 is the only improper fraction inside the set, (as in the numerator is greater than the denominator, allowing it to be simplified into a mixed fraction).
All other are proper fractions.

Answer:
about 28
Step-by-step explanation:
you have to use the sine rule = side you know * ( sin of angle opposing the side you want to know / sin of angle opposing the side you know)
AB = 19* (sin 75/ sin ( 180 -75-64) )
AB = 19 * ( sin 75 / sin 41) ≈ 27.9739...
Answer:
The answer is 3.75 or 3 3/4
