In circle K, what is the value of x? x = 30° x = 25° x = 20° x = 15º A triangle inscribed in a circle having one side as diamete
mrs_skeptik [129]

Answer:

x = 15°

Step-by-step explanation:

<em><u>The segment is a diameter, So let us assume the part in which there lies the triangle as a semicircle.</u></em>

=> <em>A triangle inscribed in a semi-circle will always have one of its angle equal to 90</em>

=> <em>So the angle (not 75 and x) is 90 degrees.</em>

<em>=> To find the value of x, we'll subtract rest of the angles from 180 degrees (because the interior angles of a triangle add up to 180°)</em>

<em>So,</em>

=> x = 180-90-75

=> x = 15°

The # of taxi accidents is approximated by y = -143.3x^2 + 1823.3x + 6820 and the # of injuries is approximated by y = -416.72x^
spin [16.1K]
To analyze the problem first is to arrange the equations according to their uses:
# of taxi accident y = -143.3X^2+1823.3x+6820
# of injuries y = -416.72X^2+4416.7x+8500
So the answer if X = 9 will be represented by 1999
# of taxi accident y = 11622.4
# of injuries y = 14495.98
I hope you understand the answer and feel free to ask for more.
