Question from Jo: Find the angle between the two sides of length 5 in an isosceles triangle that has one side of length 9 and two sides of length 5. |
Hi Jo,
I can help get you started.
Draw a line from the vertex $P$ of the triangle where the two sides of length 5 inches meet to the midpoint $Q$ of the opposite side.
What do you know about triangle $PQR?$
