In the diagram shown, it is known that RP is perpendicular to QS and RP bisects angle SRQ. If angle SRQ is 104 degrees, then explain why angle S is 38 degrees. pls help

Answer/Step-by-step explanation:
Since RP is perpendicular to QS, the angle formed is a right angle, therefore,
m<SPR = 90°
Since RP bisects <SRQ, which measures 104°, therefore,
m<SRP = ½*104°
m<SRP = 52°
m<S + m<SPR + m<SRP = 180° (sum of ∆)
m<S + 90° + 52° = 180° (substitution)
m<S + 142° = 180°
Subtract 142 from each side
m<S = 180° - 142°
Therefore:
m<S = 38°
Angles in a triangle may or may not be congruent.
[tex]\mathbf{\angle S}[/tex] is 38 degrees because [tex]\mathbf{\angle S}[/tex] is one of the base angles of an isosceles triangle.
From the question, we have:
[tex]\mathbf{\angle SRQ = 104^o}[/tex]
The sum of angles in a triangle is 180.
So, we have:
[tex]\mathbf{\angle SRQ + \angle S + \angle Q = 180}[/tex]
and
[tex]\mathbf{\angle S = \angle Q }[/tex] --- base angles of an isosceles triangle.
So, we have:
[tex]\mathbf{104 + \angle S + \angle S = 180}[/tex]
Subtract 104 from both sides
[tex]\mathbf{2\angle S = 76}[/tex]
Divide both sides by 2
[tex]\mathbf{\angle S = 38}[/tex]
Hence, [tex]\mathbf{\angle S}[/tex] is 38 degrees because [tex]\mathbf{\angle S}[/tex] is one of the base angles of an isosceles triangle.
