Answer:

solution

by using pythagorus theorem

h^2 =p^2 +b^2

  • 10^2 = p^2 +under root 82 square

therefore p is equal to

[tex]3 \sqrt{2} \\ [/tex]

sine E =p/h

=

[tex]3 \sqrt{2} \div 10[/tex]
hyp = 10
adj = √82

√82 ² + opp² = 10²

82 + opp² = 100

opp² = 100-82

opp = √18


Sin E = √18 / 10

E = 25.6°
