Answer:

b = 8 * Tan 30

Step-by-step explanation:

Points to remember

<u>Trigonometric ratio</u>

Tan θ = Opposite side/Adjacent side

From the figure we can see that a right angled triangle ABC

Bc = 8ft, <C = 90° and  <B = 30°

<u>To find the equation of finding the b</u>

We have,

Tan θ = Opposite side/Adjacent side

Tan 30 = AC/BC  = b/8

b = 8 * Tan 30

Using the law of tangents:

Tan(angle) = Opposite leg / Adjacent leg

Tan(30) = b / 8

Rewrite to solve for b:

b = 8 * tan(30)

The first answer is correct.

A system of equations has definitely many solutions. If 2y-4x=6 is one of the equations, which could be the other equation?
NISA [10]

The given equation is ⇒⇒⇒ 2y - 4x = 6

∴ 2y = 4x + 6   ⇒ divide all the equation over 2

∴ y = 2x + 3  and it can be written as ⇒⇒⇒ y - 2x = 3

The last equation represents a straight line with a slope = 2 and y-intercept = 3

To construct a system of equations with definitely many solutions and the equation ( 2y-4x=6 ) is one of the equations, the other equation must have the same slope and the same y-intercept.

so, the general solution of the other equation is ⇒ a ( y - 2x ) = 3a

Where a is constant and belongs to R ( All real numbers )

The system of equations which has definitely many solutions is consisting of <u>Coincident lines.</u>

Radio signals travel at a rate of 3 x 10^8 meters per second. How many seconds would it take for a radio signal to travel from a
wel
Time = Distance / Speed   [ Already mentioned ]

Then, substitute the known values, 

t = (9.6 × 10⁶) / (3 × 10⁸)

t = 3.2 × 10⁻² s

In short, Your Answer would be Option B

Hope this helps!
