For questions 5 and 6 the angle of the arc will always be half of the total angle of the outer edge of a circle. So for 5 you divide 194 by 2 which gives you 97.
For 6 is the same so divide 144 by 2 which is 72
7 and 8 are different questions from 5 and 6 and use their own method for a solution.
7 requires understanding that opposite angles when lines are crossed equal each other. For 7 the two angles will be 85 and opposite it is 85 so add them together and subtract from 360 which is the total angle of a circle. Which is 190 and divide that by 2 which is 95. So angle D for 7 is 95 degrees. 8 is just an opposite angle so it’s 120 degrees

Step-by-step explanation:

well,

(y - 7)² = (y - 7)(y - 7)

remember how to multiply 2 expressions ?

you have to multiply every term of one expression with every term of the other expression and sum the results all up (incl. considering their individual signs, of course).

so, when we do the multiplication, we get

(y - 7)(y - 7) = y×y - 7×y - 7×y + (-7)×(-7) =

= y² - 14y + 49

and that is clearly different to y² - 49

FYI

y² - 49 is the result of

(y - 7)(y + 7)

because

y×y + 7×y - 7×y + (-7)(7) = y² - 49

Is there any other point on the circumference of the circle that shares the y-coordinate of point A(x, y)? If so, what are the c
Feliz [49]

Answer:

  point "i" has coordinates (-x, y)

Step-by-step explanation:

Any point on the horizontal line containing point A will have the same y-coordinate. It appears that point "i" in the diagram is a point on the circle and on the horizontal line, so is the point you're looking for. Because the circle is centered at the origin, point "i" will have an x-coordinate that is the opposite of that of point A.

Point "i" is such a point. It has coordinates (-x, y).
