What Concept To Be Used When Finding Then Unkown Parts Of A Right Triangle?,

What concept to be used when finding then unkown parts of a right triangle?

 

You would use the Pythagorean theorem

A^ 2 + B^2 = C^2

example : the hypotenuse is 10^2 cm and one of the legs is 6^2 cm. What is the length of the missing leg?                               X is the unknown

6^2 = 36

10^2 = 100

                                                                 now we check our work:

6^2 + x^2 = 10^2                                       6^2 + 8^2 = x^2                                

  1. 36 + x^2 = 100                                 36 + 64  = x^2
  2. -36             -36                                  x^2 = 100
  3. x^2 = 64                                            √(100 = 10
  4. √(64 = 8

Antoine Stands On A Balcony And Throws A Ball To His Dog, Who Is At Ground Level., "The Balls Height (In Meters Above The Ground), Xxx Seconds After A

Antoine stands on a balcony and throws a ball to his dog, who is at ground level. The balls height (in meters above the ground), xxx seconds after Antoine threw it, is modeled by: h(x)=-2x^2+4x+16h(x)=−2x 2 +4x+16h, left parenthesis, x, right parenthesis, equals, minus, 2, x, start superscript, 2, end superscript, plus, 4, x, plus, 16 How many seconds after being thrown will the ball hit the ground?   Answer: The ball hit the ground after 4 seconds. Step-by-step explanation: Model of parabola of the ball thrown to the dog from the balcony: h(x)=-2x²+4x+16 Where: h(x) is the height of the ball from the balcony at x seconds y-intercep t is the height of the balcony from the ground ⇒ 16 meters To solve for the time the ball reaches the dog on the ground, solve for x. Set h(x) at 0 meters on ground level. -2x²+4x+16 = 0 Factor the equation: -2(x - 4) (x + 2) = 0 Find the x, the time in seconds: x - 4 = 0 x = 4 x +2 = 0 x = -2 Choose the positive value for time: The ball...
