Midpoint= ((X1+X2)/2,(Y1+Y2)/2)

Find the x value of the midpoint

Xm=(X1+X2)/2

Xm=(2+2)/2=2

Find the Y value of the midpoint

Ym=(Y1+Y2)/2

Ym=(3+-2)/2=0.5

The midpoint is: (2,0.5)

P2 (2,-2)

Midpoint (2,0.5)

The length of the black line is the distance between the points (5)

The angle of elevation of an unfinished tower from a point of 120m away from its base is 25 degrees. How much higher will the to

Sav [38]

Answer:

44.73 m

Step-by-step explanation:

Given that the angle of elevation of an unfinished tower from a point of 120m away from its base is 25 degrees.

Using trigonometry ratio, the height of the tower can be calculated by

Tan Ø = height / base

Tan 25 = height / 120

Make height the subject of formula

Height = 120 × tan 25

Height = 55.96 m

How much higher will the tower need to be raised so that its angle of elevation from the same point will be 40 degrees?

Using the same formula to calculate the new height.

Tan 40 = new height / base

Tan 40 = new height / 120

Make the new height the subject of the formula.

New height = 120 × tan 40

New height = 100.69 m

Increase in height = new height - height

Increase in height = 100.69 - 55.96

Increase in height = 44.73m

Therefore, the tower will need 44.73m to be raised so that its angle of elevation from the same point will be 40 degrees.

0.8% of 150 is what numbers and how do you write the equation with a variable in it.

Tanzania [10]

Answer:

1.2

Step-by-step explanation:

1. First, we have to write an equation with a variable! Given 0.8%, we know that it's equal to (0.8/100), and "of" means to multiply. Therefore, the equation will looks like this: $\frac{0.8}{100} * 150 = x$

2. Now, let's solve for x!

$\frac{0.8}{100} * 150 = (0.008)(150)$
$(0.008)(150) = \frac{6}{5}$
$\frac{6}{5} = 1\frac{1}{5}$
$1\frac{1}{5} = 1.2$
$1.2$

Therefore, 0.8% of 150 is 1.2!

Question 2 Multiple Choice Worth 5 points)

DerKrebs [107]

Answer:

√20 units.

Step-by-step explanation:

Please see attached photo for diagram.

The other leg of the triangle is x as shown in the attached photo.

Using the pythagoras theory, we can obtain the the value of x as follow:

x² = 4² + 2²

x² = 16 + 4

x² = 20

Take the square root of both side.

x = √20 units

Therefore, the value of the other leg x of the triangle is √20 units
