What is the sum of the given polynomials in standard form?

(x2 – 3x) + (–2x2 + 5x – 3)

a –3x2 + 8x – 3
b –x2 – 2x – 3
c 3x2 – 8x + 3
d –x2 + 2x – 3

Find the measure of angle y. round your answer to the nearest hundredth. ( type the numerical answer only) a right triangle is shown with one leg measuring 5 and another leg measuring 14. an angle across from the leg measuring 5 is marked y degrees. numerical answers expected!
