Answer:

[tex]43.87^{\circ}[/tex]

Step-by-step explanation:

We are given that

Height of mountain=350 m

Distance  from the tree to the skier=505 m

We have to find the angle of depression from where the skier is standing to the base of the tree.

In triangle ABC

[tex]\frac{AB}{AC}=sin\theta[/tex]

By using the formula

[tex]\frac{Perpendicular\;side}{Hypotenuse}=sin\theta[/tex]

[tex]\frac{350}{505}=sin\theta[/tex]

[tex]sin^{-1}(\frac{350}{505})=\theta[/tex]

[tex]\theta=43.87^{\circ}[/tex]

Hence, the angle of depression from where the skier is standing to the base of the tree=[tex]43.87^{\circ}[/tex]

Answer:

The value of -18x + 30y is -27

Step-by-step explanation:

Algebraic Expressions

It's given that:

6x - 10y = 9

We are required to find the value of

-18x + 30y

The easiest way to solve the problem is to visualize that:

-18x = -3(6x)

30y = -3(-10y)

This means that the second expression is equal to the first expression multiplied by -3, thus:

-18x + 30y = -3(6x - 10y) = -3*9 = -27

The value of -18x + 30y is -27

Answer:

The square root is 5 units.

Step-by-step explanation:

It is given that:

Square area is 25 units square.

We have to find the square root.

Square root = [tex]\sqrt{25}[/tex]

Square root = [tex]\sqrt{5*5}[/tex]

Square root = 5 units

Therefore,

The square root is 5 units.

when looking at the x column i will pick a couple of sets and plug them in to see if they fit and -1×4+1= -3

Answer:

x = 4

Step-by-step explanation:

5x -7 + 2x = 4x + 5

Combine like terms

5x + 2x -7 = 4x + 5

7x - 7 = 4x + 5

Combine like terms again

-4x + 7x - 7 = 4x - 4x + 5

3x - 7 = 5

3x = 5 + 7

3x = 12

Divide by 3 both sides

3x/3 = 12/3

x = 4

Hope this helps!! :)

Answer:

Angle 1

Step-by-step explanation:

The angle supplementary to 5 is 1 because two angles are supplementary when they add up to 180 degrees.

So therefore, on the other/opposite side of angle 5 is angle 1.

The supplementary angle to ∠5 is D. ∠6 as the sum of this two angles is 180°.

We know when a transversal intersects two parallel lines at two distinct points,

Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.

We know two angles are supplementary if the sum of their measure is 180°.

Now, From the given diagram we can conclude that a straight line is forming with ∠5 and ∠6, So the sum of these angles must be 180° hence supplementary.

Therefore, The angle supplementary to ∠5 is ∠6.
