Answer:

The answer to your question is VW = 2.2

Step-by-step explanation:

Data

angle = 63°

hypotenuse = ?

adjacent side = 1

Process

To solve this problem use trigonometric functions, the trigonometric function that relates the adjacent side and the hypotenuse is cosine.

cos α = $\frac{adjacent side}{hypotenuse}$

solve for hypotenuse

hypotenuse = $\frac{adjacent side}{cos \alpha}$

Substitution

hypotenuse = $\frac{1}{cos 63}$

Simplification

hypotenuse = $\frac{1}{0.45}$

Result

hypotenuse = 2.2

Answer:

Step-by-step explanation:

Triangle UVW is a right angle triangle.

From the given right angle triangle

VW represents the hypotenuse of the right angle triangle.

With ∠W as the reference angle,

UW represents the adjacent side of the right angle triangle.

UV represents the opposite side of the right angle triangle.

To determine VW, we would apply the cosine trigonometric ratio. It is expressed as

Cos θ = adjacent side/hypotenuse. Therefore,

Cos 63 = 1/VW

VWCos63 = 1

VW = 1/Cos 63 = 1/0.4540

VW = 2.2 to the nearest tenth

Sav [38]

Answer:

The length of the diagonal of the trunk is 56.356011 inches

Step-by-step explanation:

According to the given data we have the following:

height of the trunk= 26 inches

length of the trunk= 50 inches

According to the Pythagorean theorem, to calculate the length of the diagonal of the trunk we would have to calculate the following formula:

length of the diagonal of the trunk=√(height of the trunk∧2+length of the trunk∧2)

Therefore, length of the diagonal of the trunk=√(26∧2+50∧2)

length of the diagonal of the trunk=√3176

length of the diagonal of the trunk=56.356011

The length of the diagonal of the trunk is 56.356011 inches

Solve the system of equations using substitution and Elimination

Answer:

y = $\frac{-18}{7}$ and x = $\frac{50}{7}$

Step-by-step explanation:

To solve simultaneous equations, you need to have the number in front of both x's or y's the same. (signs doesn't matter)

To get -x to -10x we simply need to multiply the first equation by 10:

-x * 10 = -10x

-9y * 10 = -90y

16 * 10 = 160

-10x - 90y = 160

Now we can add the two equations:

-10x + 10x = 0

-90y + 20y = -70y

160 + 20 = 180

-70y = 180

70y = -180

7y = -18

y = $\frac{-18}{7}$

Now plug $\frac{-18}{7}$ into the second equation:

10x + 20( $\frac{-18}{7}$ ) = 20

10x - $\frac{360}{7}$ = 20

Move the $\frac{360}{7}$ over to the other side, making it a positive:

10x = 20 + $\frac{360}{7}$

10x = $\frac{500}{7}$

Divide both sides by 10:

x = $\frac{50}{7}$

So y = $\frac{-18}{7}$ and x = $\frac{50}{7}$
