Simplify the following 7 times the square root of 54 - 2 times the square root of 24

EleoNora [17]

The first step for solving this problem is to simplify the radical
7 $\sqrt{54 - 2}$ x 2√6
Calculate the product
14 $\sqrt{(54 - 2) X 6}$
Subtract the numbers
14 $\sqrt{56 x 6}$
Simplify the radical
14 x 2 $\sqrt{13 x 6}$
Multiply the numbers
14 x 2√78
Finally,, calculate the product for your final answer
28√78

A central angle θ in a circle of radius 5 m is subtended by an arc of length 6 m.

Marina86 [1]

Answer:

θ=1.2 rad=68.7549°

Step-by-step explanation:

Given

Circle of radius 5
Arc of length 6 subtends angle of θ

$\text{Arc Length}=\text{Radius}\times \text{Angle Subtented(in rad)}$

⇒

$6= 5\times \text{O}\\$

θ $=\frac{6}{5} =1.2rad$

Therefore θ=1.2 rad

(π rad= 180°)

Therefore 1.2 rad= 68.7549°

Answer:

There are two solutions!

a = 48.80524 degrees

or

a = 131.19476 degrees

Step-by-step explanation:

A = sin^-1 (sinB * 1/b) = sin^-1 * (sin(38degrees) * 11/9. =. sin^-1 (0.75)

^ is used to signify to the __ power

8) in the diagram below the distance of AC is X+32. Find the value of AB.

Svetradugi [14.3K]

13+2x+12=x+32
25+2x=x+32
X=7
So AB would be 27
