Step-by-step explanation:

Which of the expressions belowWhich of the expressions below is equal to x2 + 2x – 15? Select all that apply. A) x² + x- 8 + x-7 B) (x-3)(x + 5) C) (r + 2 + 15 D) p2 + x + x2 + x-15​

is equal to x2 + 2x – 15? Select all that apply. A) x² + x- 8 + x-7 B) (x-3)(x + 5) C) (r + 2 + 15 D) p2 + x + x2 + x-15​

Which of the expressions below is equal to x2 + 2x – 15? Select all that apply. A) x² + x- 8 + x-7 B) (x-3)(x + 5) C) (r + 2 + 15 D) p2 + x + x2 + x-15​

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
