Answer:
34.868
Step-by-step explanation:
P[tex]H^{2} =P^{2} -B^{2}[/tex]
X[tex]x^{2} =(20)^{2}+(Y)^{2}[/tex]..............................(i)
WE KNOW,
COS35 = [tex]\frac{Y}{X}[/tex]...................................(ii)
taking the value of eqn (ii) to eqn (i)
[tex]x^{2} =400+0.6710100717x^{2} \\
x^{2} = \frac{400}{0.3289899283}\\
x^{2} = 1215.842692\\
x=34.868[/tex]
