Question

El valor numerico de: E= 2cos60⁰ + tan²45⁰
_____________
sec²60⁰- 2tan45⁰​

Answer 1

$e \: = \: \frac{2cos(60°) \: + \: tan (45°) ^{2} }{sec (60 °) ^{2} \: - \: 2tan(45°)}$

$e \: = \: \frac{2 \: \times \: \frac{1}{2} \: + \: {1}^{2} }{ {2}^{2} \: - \: 2 \: \times \: 1 }$

$e \: = \: \frac{1 \: + \: 1}{4 \: - \: 2}$

$e \: = \: \frac{2}{2}$

$e \: = \: 1$
