Answer:
x = 40
Step-by-step explanation:
Given 2 secants to a circle from an external point, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
8(8 + x) = 12(12 + 20) ← distribute parenthesis on both sides
64 + 8x = 12 × 32 = 384 ( subtract 64 from both sides )
8x = 320 ( divide both sides by 8 )
x = 40
Multiply 245 by .40 (which is 40%)
245 x (.40)= 98. When you get 98, you have to 245-98 and you get 147
Answer:
Moving point D does not change the measures of the inscribed angle or the central angle . It simply changes the position of the inscribed angle on the coordinate plane . My conclusion in Question 4 still hold true : the inscribed angle is half the measure of the corresponding central angle .
