During an experiment, Aika measured the time it took for a ball to roll down a ramp set at an angle. She measured that it took 1

schepotkina [342]

Answer:

11.725%

Step-by-step explanation:

Given that :

True value = 0.904 seconds

Measured time = 1.010 seconds

Experimental error :

(|measured value - True value | / true value) * 100%

(|1.010 - 0.904| ÷ 0.904) * 100%

= 0.106 / 0.904 * 100%

= 0.1172566 * 100%

= 11.725%

Identify the angle relationship, write an equation and Solve for x.

irakobra [83]

Answer:

$2x-6+x+x=180$

$4x-6=180$

$4x=180+6$

$4x=186$

$x=\frac{186}{4}=46,5°$

Step-by-step explanation: the other angle is equal to his simmetrical, cause the triangle is isosceles, so is value is x. The sum of the angle in a triangle must be 180°
