Ineed with both of these questions. 1. find the length of side b to two decimal places. 2. find the length of side a to two decimal places.

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.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

answer: i don't understand it
