Answer:

x=0

Step-by-step explanation:

it tells you that

∠LKJ=169

∠SKJ=x+95

∠LKS=74+2x

and by the figure we know that

∠LKJ=∠LKS+∠SKJ

so we have

169=x+95+74+2x\\\\169=3x+169\\\\169-169=3x\\\\0=3x\\\\x=0

LKS + SKJ = LKJ

Substitute the numbers into the equation above.

74 + 2x + x + 95 = 169

Combine like terms

3x + 169 = 169

Subtract 169 from both sides

3x = 0

Divide both sides by 3

x = 0

SKJ = x + 95 = 0 + 95 = 95

LKS = 74 + 2x = 74 + 2(0) = 74 + 0 = 74

LKJ = 169

LKS + SKJ = LKJ

74 + 95 = 169. This proves that x = 0

a surveyor measures the distance to the two landmarks as shown in the diagram what is the distance d. between the landmarks​
Inessa [10]
<h3>The distance between two landmarks is 123 meters</h3>

<em><u>Solution:</u></em>

We have to find the distance between two landmarks

<em><u>Use the law of cosines</u></em>

The third side of a triangle can be found when we know two sides and the angle between them

c^2 = a^2 + b^2 - 2ab\ cos c

Here, angle between 90 meters and 130 meters is 65 degrees

From figure,

a = 90

b = 130

c = d

Therefore,

d^2 = 90^2 + 130^2 - 2(90)(130)\ cos 65\\\\d^2 = 8100 + 16900 - 23400\ cos\ 65\\\\d^2 = 25000 - 23400 \times 0.4226\\\\d^2 = 25000 - 9889.267\\\\d^2 = 15110.73\\\\d = 122.92\\\\d \approx 123

Thus, the distance between two landmarks is 123 meters

5|2x - 3| + 4 = 9<br> How do you solve this
agasfer [191]

Answer:

x = 2, or x = -1

Step-by-step explanation:

If 2x - 3 is inside the parenthesis (), then the value of x is 2.

If 2x - 3 is inside the absolute value sign, then the value of x will probably be -1.

<u>Solution 1</u>

(10x-15) + 4 = 9

10x -11 = 9

10x = 20    -> x = 2

<u>Solution 2</u> (Not 100% sure)

|10x -15| +4 = 9

10x + 15 +4 = 9

10x + 19 = 9

10x = -10      -> x = -1

Please correct me if I'm wrong.

If it took 6 hours to clean 12 houses, how many houses could be cleaned in 11 hours?
nata0808 [166]

22 houses can be cleaned in 11 hours.

Step-by-step explanation:

It is given that;

6 hours = 12 houses cleaned

1 hour = \frac{12}{6}\ houses\ cleaned\\

1 hour = 2 houses cleaned

In 1 hour, 2 houses can be cleaned, therefore,

11 hours = Time*houses cleaned in one hour

11 hours = 11*2 =22 houses cleaned

22 houses can be cleaned in 11 hours.
