Pasos de solución

(0.5) (9.8) = (0.45) (9.8) sin (θ)

Intercambiar lados

0.45 \cdot 9.8 sin (θ) = 0.5 \cdot 9.8

Multiplicar los numeros:

0.5 \cdot 9.8 = 4.9

0.45 \cdot 9.8 sin (θ) = 4.9

Multiplicar ambos lados por

100

0.45 \cdot 9.8 sin (θ) = 4.9

To eliminate decimal points, multiply by 10 for every digit after the decimal pointThere are

2

digits to the right of the decimal point, therefore multiply by

100

0.45 \cdot 9.8 sin (θ) \cdot 100 = 4.9 \cdot 100

Simplificar

441 sin (θ) = 490

441 sin (θ) = 490

Dividir ambos lados entre

441

441 sin (θ) = 490

Dividir ambos lados entre

441

\frac{441 sin ( θ )}{441} = \frac{490}{441}

Simplificar

sin (θ) = \frac{10}{9}

sin (θ) = \frac{10}{9}

- 1 \leq sin (x) \leq 1

Sin soluci \overset{o}{ˊ} n para θ \in R

tan (θ) = - 1.732

sin (\frac{θ}{2}) + cos (θ) = 0

cos (θ) = - 0.75

4 cos (x) = 2 sin (x)

cos (x) + \frac{2}{2} = 0
