Tamiku [17]

Answer:

x = 12 degrees

Step-by-step explanation:

m < LNM = (70+136)/2

= 206 / 2

= 103 degrees

So 7x + 19 = 103

7x = 103 - 19 = 84

x = 84/7

x = 12.

An inscribed triangle with the hypotenuse being the diameter of the circle has angle A be 42 degrees. Angle C is 90 degrees. The
eduard

Answer:

The Radius of circle is 7.15 cm  

Step-by-step explanation:

Given as :

A Triangle is inscribed into circle

The center of circle is O

The Diameter of circle = AK = d

The hypotenuse of triangle being the diameter of circle

The Area of triangle = 50 cm²

Let The radius of circle = r cm

The Triangle is right angle at c

So , ∠ACK = 90°

∠CAK = 42°

∠AKC = 180° - (90° + 42°)

So, ∠AKC = 48°

Now, ∵ Area of triangle ACK = 50 cm²

So, \dfrac{1}{2} × AC × CK = 50

Or, AC × CK = 50 × 2

i.e , AC × CK = 100        ..........1

From figure

Sin 48° =  \dfrac{AC}{AK}

Or, 0.74 =  \dfrac{AC}{d}

∴ AC = 0.74 d             ..........2

<u>Similarly</u>

Sin 42° =  \dfrac{CK}{AK}

Or, 0.66 =  \dfrac{CK}{d}

∴ CK = 0.66 d               .............3

<u>Putting eq 2 and 3 value into eq 1</u>

i.e  AC × CK = 100  

Or, 0.74 d  × 0.66 d = 100  

Or, 0.4884 × d² = 100  

∴ d² = \dfrac{100}{0.4884}

Or, d² = 204.75

Or, d = \sqrt{204.75}

Or, d = 14.30

So, The diameter of circle = d = 14.30 cm

Now, Radius of circle = \dfrac{\textrm diameter}{2}

Or, r =  \dfrac{\textrm 14.30 cm}{2}

i.e r = 7.15 cm

So, The Radius of circle =  r = 7.15 cm

Hence, The Radius of circle is 7.15 cm  Answer

If a ball has a rebound ratio of 0, what does that mean?
exis [7]

Answer: The test is conducted with an electromagnetic or vacuum release mechanism which releases a soccer ball from a height of 2 meters. From that the height of the rebound is measured by recording the sound of the first and second bounce. The time between the first and second bounce is measured. Also During a collision, some of the ball's energy is converted into heat. As no energy is added to the ball, the ball bounces back with less kinetic energy and cannot reach quite the same height. ... It reaches way higher than from the height it was released.
