Answer: 8 units (7.81 Units without rounding)

Work: To get this answers, you need to know the Pythagorean Theorem. The Pythagorean Theorem is a² + b² = c² (c² being the length you need to find) After you find the answer, you have to square it, and after squaring it, you get the missing length. So, let's plug in the numbers. 5² + 6² = 61. Now we need to √61. After doing so, you get 7.81024..., and if you round half way, you get 7.81 units. But preferably, I like to round fully, and you get 8 units.

I hope this helps, and Happy Holidays! :)

11. angle MLN and angle JLK are complementary, m angle MLN=7x-1 and m angle JLK=4x+3 . a. Solve for x b. Find m angle MLN and m

Natali [406]

a. Solve for x

Since angle MLN and angle JKL are complementary, the value of x = 8

Since angle MLN and angle JKL are complementary, their sum equal 90°.

Since angle MLN = 7x - 1 and angle JKL = 4x + 3, we have that

7x - 1 + 4x + 3 = 90

Collecting like terms, we have

7x + 4x - 1 + 3 = 90

Simplifying, we have

11x + 2 = 90

Subtracting 2 from both sides, we have

11x = 90 - 2

11x = 88

Dividing through by 11, we have

x = 88/11

x = 8

So, Since angle MLN and angle JKL are complementary, the value of x = 8

b. Find m angle MLN and m angle JKL .

Since angle MLN=7x-1 and angle JLK=4x+3 thus, angle MLN = 55° and angle JKL = 35°

Since angle MLN = 7x - 1 and x = 8, we have

angle MLN = 7x - 1

angle MLN = 7(8) - 1

angle MLN = 56 - 1

angle MLN = 55°

Since angle JKL = 4x + 3 and x = 8, we have

angle JKL = 4x + 3

angle JKL = 4(8) + 3

angle JKL = 32 + 3

angle JKL = 35°

So, Since angle MLN=7x-1 and angle JLK=4x+3 thus, angle MLN = 55° and angle JKL = 35°

El horario y el minutero de un reloj miden respectivamente 0.7 y 1.2cm. Determinar la distancia entre los extremos de dichas man

Fed [463]

Answer:

1.5887 cm

Step-by-step explanation:

If the time is 13:30, The hour pointer will be between the numbers 1 and 2.

Each number of the 12 number clock is separated by 30 degrees, so the hour pointer is at 45 degrees.

The minute pointer is at 30 minutes, so it is in number 6, being therefore at angle 180.

The angle formed by the pointers will be 180 - 45 = 135 degrees.

We can draw a triangle with both pointers and this angle (image attached)

So, we can calculate the distance between the tip of the pointers (let's call it "d") using law of cosines:

d^2 = 0.7^2 + 1.2^2 - 0.7*1.2*cos(135)

d^2 = 0.49 + 1.44 - (-0.5940) = 2.524

d = 1.5887 cm
