Question

in figure, o is the orgin and A (8, 0), B (0, 6) are two points
(a) write the coordinates of the circle with A B as diameter.
(b) write the equation of the circle.
(c) if one end of the diameter of this circle is the orgin, write the coordinates of the other end of this diameter.
ANSWER THE QUESTION

Answer 1

Answer:

In △ABC AB=AC

⇒∠B=∠C (Angles opposite to equal sides are equal)

Now using angle sum property

∠A+∠B+∠C=180

∘

⇒80

∘

+∠C+∠C=180

∘

⇒2∠C=180

∘

−80

∘

⇒∠C=

2

100

∘

=50

∘

now ∠C+∠x=180

∘

(Angles made on straight line (AC) are supplementary)

⇒50

∘

+∠x=180

∘

⇒∠x=180

∘

−50

∘

=130
