From the inscribed circle, AE and AD are the radius of the circle while BE and BD are the tangents.
<h3>What is an inscribed circle?</h3>
An inscribed circle simply means the largest circle that's contained in a triangle.
An inscribed circle touches its tangent to the three sides. In this case, AE and AD are the radius of the circle while BE and BD are the tangents. Also, angle ABE and ABD are 60°.

If you divide 15 by 12 (the difference between the prices) then that's what you get :)
Answer:
A
Step-by-step explanation:
Answer:
a) Yes
b) Not a right triangle
Step-by-step explanation:
<h3><u>Part (a)</u></h3>
The sum of the lengths of any 2 sides of a triangle is greater than the length of the 3rd side.
7 + 8 = 15 > 9
7 + 9 = 16 > 8
8 + 9 = 17 > 7
Therefore, a triangle with side lengths 7, 8 and 9 <u>can</u> be made.
<h3><u>Part (b)</u></h3>
To determine if the triangle is a right triangle, use Pythagoras' Theorem:
a² + b² = c² (where a and b are the legs, and c is the hypotenuse)
The hypotenuse is the longest side, therefore:
Substituting these values into the formula:
⇒ a² + b² = c²
⇒ 7² + 8² ≠ 9²
⇒ 113 ≠ 81
As 7² + 8² ≠ 9² then the triangle is <u>not</u> a right triangle.
