Answer:

\theta = 14.1\ degrees

846\ minutes

Step-by-step explanation:

Given

csc(\theta) = 4.1191

Required

Solve for \theta

csc(\theta) = 4.1191

csc(\theta) = \frac{1}{sin(\theta)}

So, we have:

\frac{1}{sin(\theta)} = 4.1191

Invert both sides

sin(\theta) = \frac{1}{4.1191}

sin(\theta) = 0.2428

Take sin^{-1} of both sides

sin^{-1} sin(\theta) = sin^{-1}0.2428

\theta = sin^{-1}0.2428

\theta = 14.0518577574

\theta = 14.1\ degrees --- approximated

Convert to minutes:

1\ degree = 60\ minutes

So:

14.1\ degrees = 14.1 * 60\ minutes

14.1\ degrees = 846\ minutes

Ray is constructing a flowerbed for the zoo and wants to
faust18 [17]

Answer:

Option (3)

Step-by-step explanation:

Since, flowerbed is in the shape of a right triangle,

By applying Pythagoras theorem in the given right triangle,

(Hypotenuse)² = (leg 1)² + (leg 2)²

(Hypotenuse)² = (12)² + (12)²

(Hypotenuse)² = 144 + 144

Hypotenuse = √288

Hypotenuse = 16.97

                     ≈ 17 ft

Perimeter of the triangle = Sum of the measures of three sides of the triangle

= 12 + 12 + 17

= 41 ft

Therefore, Option (3) will be the correct option.

FInd the solution for 4(x - 5)=2(x - 10) +2x
crimeas [40]
Hello!

You solve this like an algebraic equation

You first distribute the 4 and 2

4x - 20 = 2x - 20 + 2x

Combine like terms

4x - 20 = 4x - 20

subtract 4x from both sides

-20 = 0x - 20

Add 20 to both sides

0 = 0

This means that there are infinite solutions to the equation.

Hope this helps!
