marta [7]

Answer:

\% Change = \frac{|120-200|}{200} *100 = 40\%

And the interpretation for this value is that the oak tree is have a height of 40% lower than the Redwood tree

Step-by-step explanation:

For this case we can calculate the % of change with the formula of relative change given by:

\% Change = \frac{|New -Base|}{Base} *100

For this case the Base value is 200 ft since represent the heigth of the redwood tree selected as the base

And the New value would be 120 who represent the height of the oak tree

If we replace into the formula we got:

\% Change = \frac{|120-200|}{200} *100 = 40\%

And the interpretation for this value is that the oak tree is have a height of 40% lower than the Redwood tree

Find the value of x.
serg [7]

Answer:

x = 25

Step-by-step explanation:

The Exterior Angle Theorem states that the exterior angle of a triangle is equal to the sum of the two opposite interior angles.

This means that

3x - 10 = 25 + (x+15)

3x - 10 = x + 40

Subtract x from both sides of the equation.

2x - 10 = 40

Add 10 to both sides.

2x = 50

Divide both sides by 2.

x = 25
