Answer:

  x = 3.6

Step-by-step explanation:

The angle bisector divides the segments proportionally. This means they satisfy ...

  bottom segment / side segment = x/6 = (6-x)/4

Multiplying by 12 gives ...

  2x = 3(6 -x)

  2x = 18 -3x . . . . . eliminate parentheses

  5x = 18 . . . . . . . . add 3x

  x = 3.6 . . . . . . . . . divide by 5

_____

Alternate solution

I like to try to work these mentally. The total of side lengths is 10, so the total base length (6) is 6/10 = 0.6 times that. Then x will be 0.6 times the left side length: 0.6·6 = 3.6 = x.

The points (11, 13) and (7, 13) fall on a particular line. What is its equation in slope-intercept form?

Answers

Answer:

slope -intercept form y=mx+c

The equation of the straight line

                                 y = 0x +13

Step-by-step explanation:

Step(i):-

Given that the points

           (11 ,13) and (7,13)

The slope of the line

    [tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{13-13}{7-11} = \frac{0}{-4} =0[/tex]

Step(ii):-

Equation of the straight line passing through the point (11,13) and slope m=0

y - y₁ = m( x-x₁)

y - 13 =0(x-11)

y-13 =0

y =13

slope -intercept form y=mx+c

y = 0x +13

Find the altitude of the triangle.
30 degrees
Hypotenuse of 14

Answers

Answer:

Approx. 12.124 units tall

Step-by-step explanation:

Since you need to find the height (which is adjacent to the given angle), you need to use cosine (adj. over hypotenuse).

cos(30) = x/14

Multiply both sides by 14:

14cos(30) = x

It is a 30 60 90 triangle, therefore you should use the 30:60:90 triangle rule; 1: sqrt(3) : 2

Since in this triangle the side opposite of the 90 degree angle is 14, we know the side opposite the 30 degree angle is 14/2 = 7
Then, we multiply 7 by sqrt(3) and get 7sqrt(3) as the side opposite the 60 degree angle.

Step-by-step explanation:

You want me to let you in on a secret? There's a simple equation that you can use to solve any quadratic problem in a minute or two.

It's the quadratic formula

x =  [tex]x = \frac{-b +- \sqrt{b^2 - 4ac} }{2a}[/tex]

The +- means that you will do this two times, the first time you will do -b + sqrt(b^2-4ac), and the second time you will do minus that.

a is the coefficient of the first term in the expression, b is the second and c is the third.

so we get[tex]x = \frac{-(-10) +- \sqrt{(-10)^2 - 4(1)(24)} }{2(1)}[/tex] , which is the same as

[tex]x = \frac{10 + \sqrt{100 - 24(4)} }{2}[/tex]

and

x = [tex]x = \frac{10 - \sqrt{100 - 24(4)} }{2}[/tex]

The top part simplifies to [tex]\frac{10 + \sqrt{100 - 72} }{2} = \frac{10 + 6}{2} = 5[/tex], which is your answer.

Step-by-step explanation:

0.75 ⇒ 100%

0.15 ⇒ x%

0.75x = 100·(0.15)

0.75x = 15

x = 15/(0.75)

x = 1500/75

x = 20%

100% - (discount) = x%

100% - (discount) = 20%

discount = 100%-20%

discount = 80%

Answer:

JKLM ~ QRSP, scale factor 0.6ΔABC ~ ΔUVT, scale factor 1.5

Step-by-step explanation:

We can write the similarity statements by naming vertices in order of increasing numbers of arcs, starting with the one having a single arc. Then we can express the side lengths as a reduced ratio, in the same order.

1. JKLM ~ QRSP

  JK : KL : LM : MJ = 20 : 15 : 24 : 25

  QR : RS : SP : PQ = 12 : 9 : 14.4 : 15 = 20 : 15 : 24 : 25 (same ratios)

The scale factor is 12/20 = 0.6.

__

2. ΔABC ~ ΔUVT

  AB : BC : CA = 16 : 14 : 12 = 8 : 7 : 6

  UV : VT : TU = 24 : 21 : 18 = 8 : 7 : 6 (same ratios)

The scale factor is 24/16 = 1.5.

A 10 meter ladder is leaned up against a building. If
the angle of elevation is 60 degrees, what is the
height of the building?

Answers

Answer:

8.7

Step-by-step explanation:

Use trigonometry. The ladder and the building form a right triangle with the ground. You are given the length of the hypotenuse and the base angle. You use sine since we are trying to figure out the opposite side from the angle and we have the hypotenuse length. Sin = opposite/hypotenuse. So in this case, sin 60°= x/10. We solve for x by multiplying both sides by 10. Now x= sin 60° (10) = (0.8660)(10) = 8.7 m.
