Since the triangle is a right angle at BFC, wouldn’t that indicate it’s either 30°, 45°, or 60°? What are the values for the side dimensions?

Answer:

triangleBFCBis an isosceles triangle

angleBFC=90°

angle FBC and angle BCF are equal

let angle FBC=x,angleBCF=x

the sum of angles in a triangle=180°

90+x+x=180°

90+2x=180

2x=180-90

2x=90

divide both sides by 2

2x÷2=90÷2

x=45°
