Explicación paso a paso:
RICARDO:
X= 20
PR= 80
LAURA:
UTILIZAMOS ESTA FORMULA:
[tex]C^{2}= A^{2}+B^{2}[/tex]
REMPLAZAMOS:
[tex]15^{2} =10^{2} +B^{2}[/tex]
[tex]225=100+B^{2}[/tex]
225-100 =[tex]B^{2}[/tex]
125= [tex]B^{2}[/tex]
[tex]\sqrt{125}[/tex]= B
11.18 = B
ENTONCES:
X = 40 - 11,18
X = 28.82
PL = 65 + 28.82
PL = 90.82
