A 50-foot tree casts a shadow 9 feet long. The sine of the angle between the ground and the line that connects the tip of the shadow to the top of the tree is approximately...?

The equation is y=17(7)+600 and it equals 717

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
