Answer:

10

Step-by-step explanation:

This triangle is divided into 2 identical rigth triangles.

We will use the pythagorian theorem:

●8^2+ (12/2)^2 =x^2

● 64 + 36 = x^2

● x= 10

So x is 10

Answer:

x=10

Step-by-step explanation:

We can use the Pythagorean theorem to find x

The height meets the base at a right angle

The base is bisected ( cut in half) so the base is 6 the height is 8

a^2 + b^2 = c^2

6^2 + 8^2 = x^2

36+64 = x^2

100 = x^2

Taking the square root of each side

sqrt(100) = sqrt(x^2)

10 = x

What is the distance from the origin of point P graphed on the complex plane below?
ZanzabumX [31]

Answer:

b) √29

Step-by-step explanation:

Given: The origin is (0, 0), the point P is (2, -5).

We need to use the distance formula.

Distance formula = \sqrt{(x2 -x1)^2 + (y2 - y1)^2} \\

Here x2 = 2, x 1 = 0, y1 =0, y2 = -5

Distance = \sqrt{(2 -0)^2 + (-5 - 0)^2}

= \sqrt{2^2 + (5)^2}

= √(4 + 25)

= √29

The answer is b) √29

Hope you will understand the concept.

Thank you.

Answer:

A) 264 ft^2, 4 gallons

Step-by-step explanation:

Area of rectangle = 12 ft x 18 ft = 216 ft^2

Area of triangle = 1/2 (28- 18)(12) = 1/2(10)(12) = 60 ft^2

Area of window: 3 ft x 4 ft = 12 ft^2

Areas will be painting = (216 + 60) - 12 = 264 ft^2

1 gallon of paint will cover 70 ft^2 so 264 ft^2 / 70 ft^2 = 3.77 gallons

So Mr. Williams will need 4 gallons of paint to cover 264 square feet of his barn

TRIANGLE CONGRUENCE! PICTURE ADDED. How is QTP congruent to SPT?
shtirl [24]

Answer:

The triangles are congruent because:

  1. QP = ST
  2. angle P = angle T
  3. the side PT is in both triangles

We know when 2 sides of two triangles and the angle between them is congruent, the triangles are congruent.

Item 3
Kruka [31]

Answer:

The given  system as (3,3) as its solution.

Step-by-step explanation:

Here, the given system of the equation is:

4 x + 2 y = 18 ................  (1)

2 x + 3 y = 15      ...............  (2)

Now, to use the elimination method, w need to eliminate any of the variable.

Eliminate the variable x in the given system.

Multiply equation (2) with -2  we get,

(2 x + 3 y = 15  )(-2) ⇒ -4x - 6y = -30  .......  (3)

Add (1) and (3), we get:

4 x + 2 y   -4x - 6y    = 18  -30

or, - 4 y = - 12

or, y =  12/4 = 3    ⇒ y = 3

Putting in (1), we get

4x + 2(3)   = 18  or, 4x    = 18 - 6 = 12

or, x  = 3

(x,y)  = (3,3)

Hence, the above system as (3,3) as its solution.
