Answer:

s = 35pi units

We can either leave it with pi in the answer or approximate

s= 109.9557429 units

Step-by-step explanation:

Arc length is found by

s = r * theta where r is the radius and theta is given in radians

Changing the angle from 150 degrees to radians by multiplying by pi/180

150 *pi/180 = 5/6 pi

Now we can use the formula

s = 42 * 5/6 pi

s = 35pi

We can either leave it with pi in the answer or approximate

s= 109.9557429 units

artcher [175]

To solve this problem you must apply the proccedure shown below:

1. You have:

Sinα=opposite/hypotenuse

α=62°
opposite=x
hypotenuse=15 ft

2. When you substitute the values into Sinα=opposite/hypotenuse, you obtain:

Sinα=opposite/hypotenuse
Sin(62°)=x/15

3. You must clear "x", as below:

x=(15)(Sin(62°))
x=13.24 ft

The answer is. 13.24 ft

What is the error in the equation

dimulka [17.4K]

Answer:

The fifth line contains the error.

Step-by-step explanation:

Line 1 is the equation.

Lines 2, 3, and 4 are correct.

The error is in the 5th line.

The square root of a negative number is not a real number, so if this problem is solved only with real numbers, there is no solution.

If imaginary numbers are allowed, then the last line should read:

$x = \pm\dfrac{i\sqrt{11}}{2}$
