Which statements are true about the trigonometric ratios of this triangle

rosijanka [135]

Answer:

Options (1), (2), (3) and (4)

Step-by-step explanation:

By applying the sine and cosine rules in the given triangle,

sinθ = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

cosθ = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

cos(30°) = $\frac{AC}{AB}$

= $\frac{11\sqrt{3} }{22}$

= $\frac{\sqrt{3}}{2}$

sin(30°) = $\frac{BC}{AB}$

= $\frac{11}{22}$

= $\frac{1}{2}$

cos(60°) = $\frac{BC}{AB}$

= $\frac{11}{22}$

= $\frac{1}{2}$

sin(60°) = = $\frac{AC}{AB}$

= $\frac{11\sqrt{3} }{22}$

= $\frac{\sqrt{3}}{2}$

Options (1), (2), (3) and (4) are the correct options.

What is the answer to this equation? Must solve for x.<br> x+5=12x−4

natulia [17]

Answer:

x = 9/11

Step-by-step explanation:

x + 5 = 12x - 4

Subtract x from both sides

x + 5 - x = 12x - x - 4

5 = 11x - 4

Add 4 to both sides

5+ 4 = 11x - 4 + 4

9 = 11x

Divide both sides by 11

9/11 = 11x/11

9/11 = x

x = 9/11

Is this a true statement? 0.3711 > 0.3801

disa [49]

NO. It's FALSE.

$0.\ 3\ 7\ 1\ 1\\||\ ||\wedge\\0.\ 3\ 8$

therefore 0.3801 > 0.3711
