Hi,

The two forces of magnitude 24 and 7 units act at right angle.

The vector law :

Let P and Q be two vectors acting simultaneously at a point and  θ be the angle between P and Q and R be the resultant vector.

R² =P² +2PQcosθ+Q²   (magnitude)

= tan ^{- 1} ((Qsinθ/(P+Qcosθ))

Here magnitudes are 24 adn 7. θ=90°

So

The resultant of the two forces will be :

1. Magnitude : √ (24² )+(7² )= √ (576+49)= √ 625=25 units.

2. Direction; Suppose the vectors are 24i+7j, then the direction of the resultant will be:

= tan ^{- 1} (7/24) in radian.

Hope this helps!
