Answer 1

Answer:

1. $724.2sin(349)^2sin(118)$

2. $724.2sin(118)sin(1189)sin(21.3)$

3. $2513.4sin(118)sin(21.3)sin(349)$

Step-by-step explanation:

1. $21.3sin(349)sin(118)*34sin(349)$

= $724.2sin(349)^{1} sin(118)$$sin(349)^1$

= $724.2sin(349)^1^+^1sin(118)$

2. $21.3sin(118)*34sin(1189)sin(21.3)$

3. $21.3sin(118)*118sin(21.3)sin(349)$

Answer 2

A. $t = \frac{(22.3) (sin34)}{sin 118}$

There are 2 main ways in which trigonometric functions are typically discussed, in terms of the right triangles or in terms of the unit circle. The right angled triangle definition on the trigonometric functions is most often how they are introduced, or followed by their definitions in terms of the unit circle.

How to find the trigonometric functions?

• ais the length of side adjacent in to the angle (x) in question.
• ois the length of the side opposite the angle.
• his the length of the hypotenuse.

As we all know in any triangle where 2 angles and opposite sides of these 2 angles are in the ratio of $\frac{sinA}{sina} =\frac{sinB}{sinb} =\frac{sinC}{sinc}$

As we have given in the question angle A = 34° and

its opposite side is t. Angle B = 118° and b = 21.3

Now we place the values into the formula

$\frac{sin34}{t} =\frac{sin118}{21.3} \\\\t=\frac{(21.3)(sin34)}{sin118}$

Hence  option (A) is the correct option.
