Answer: The value of other side is 7.8 inch.
Explanation:
It is given that the isosceles triangle has angle measures 50°, 50°, and 80°. The side across from the 80° angle is 10 inches long.
Let the given length of other equal sides be x.
The side across from the 50° angle is x inches long.

= √(3^2 * 7)
= √(3^2) * √7
= 3 * √7
= 3√7</span>
(6,-5)(9,r)
(r - (-5) / (9 - 6) = -4
(r + 5) / 3 = -4
r + 5 = -4 * 3
r + 5 = -12
r = -12 - 5
r = - 17 <===
