Answer: Hello your question is incomplete attached below is the complete question
Ra = 1132 N
Rb = 522.6 N
Pa = 679.7 N
Explanation:
To determine the scalar components Ra
[tex]\frac{Ra}{Sin 120^o} = \frac{750}{sin 35^o}[/tex]
therefore : Ra = [tex]\frac{sin120^o * 750}{sin 35^o}[/tex] = 1132 N
To determine the scalar component Rb
[tex]\frac{Rb}{sin 25^o} = \frac{750}{sin 35^o}[/tex]
therefore : Rb = [tex]\frac{sin 25^o * 750}{sin 35^o}[/tex] = 522.6 N
To determine the orthogonal projection Pa of R onto
Pa = 750 cos[tex]25^o[/tex] = 679.7 N
