2x + 2y = -2 3x -2y = 12

PIT_PIT [208]

Answer:

$2x + 2y = - 2 \\ 3x - 2y = 12 \\ now \: add \: both \: equations \\ 2x + 2y + (3x - 2y) = - 2 + 12 \\ 2x + 2y + 3x - 2y = 10 \\ 5x = 10 \\ \frac{5x}{5} = \frac{10}{5} \\ x = 2 \\ \\ 2x + 2y = - 2 \\ 2 \times 2 + 2y = - 2 \\ 4 + 2y = - 2 \\ 2y = - 2 - 4 \\ 2y = - 6 \\ \frac{2y}{2} = \frac{ - 6}{2} \\ y = - 3 \\ now \: lets \: check \: whether \: this \: equation \: correct \\ 3x - 2y = 12 \\ 3 \times 2 - 2 \times - 3 = 12 \\ 6 + 6 = 12 \\ 12 = 12 \\ yes \: its \: correct$

HELP I NEED IT QUICK

Vladimir79 [104]

Answer:

cos27 = 2/HJ

HJ = 2/0.89

= 2.24 units

sin27 = HI/2.4

HI = 0.89×2.4

= 2.13 units

sinH = 2/2.4

= 0.833

H = sin inverse 0.833 = 56.4°

hope it helps :D
