Question from Bobbi: Isosceles Trapezoid base=60"; two 45⁰ angles at base, two 135⁰ angles at the top, vertical distance between base & top=16". What is the length of the top line and the two equal side lines? |
Hi Bobbi,
I can get you started
I drew a diagram
You know the measure of the angle BCA is 45⁰ and the measure of the angle CAD is 135⁰. What is the measure of the angle CAB? What does that tell you about the triangle ABC? What is the length of BC?
