Find the measure of d.

Mathematics
1 answer:
ad-work [718]3 years ago
3 0

Answer:

d = 123

Step-by-step explanation:

The given figure above is an inscribed quadrilateral with all four vertices lying on the given circle, thereby forming chords each.

Therefore, the opposite angles of the above quadrilateral are supplementary.

This means:

c + 31 = 180 , and

d + 57 = 180

Find the measure of d:

d + 57 = 180

Subtract 57 from both sides.

d + 57 - 57 = 180 - 57

d = 123

A = 13(7) + 9(7)

A = 22(7)

A = 22(7)

A = 20(7)+2(7)

45 units and is centered at
mariarad [96]

The correct question is:

A circle has a radius of 45 units and is centered at (-2.4, -4.8).

What is the equation of this circle?

Answer:

Equation of the circle is;

(x + 2.4)² + (y + 4.8)² = 2304

Step-by-step explanation:

The standard equation of a circle is;

(x - a)² + (y - b)²  =  r²

where;

(a,b) is the center of the circle and r is the radius of the circle

Now, from the question, the circle is centered at (-2.4, -4.8) and the radius is 45

Thus, plugging those values into the standard form of equation of a circle, we have;

(x - (-2.4))²  +  (y - (-4.8))²  = 48²

This gives;

(x + 2.4)² + (y + 4.8)² = 2304
