Mathematics

miss Akunina [59]2 years ago

Answer:

x = -4, y = 9

or

(-4, 9)

Step-by-step explanation:

x - 5y = -49

y = -2x + 1

substitute y for -2x + 1

x - 5(-2x + 1) = -49

x + 10x - 5 = - 49

add 5 to both sides

x + 10x - 5 + 5 = - 49 + 5

x + 10x = -44

11x = -44

divide both sides by 11

11x/11 = -44/11

x = -4

substitute x for -4 in any of the original equations

y = -2x + 1

y = -2 * -4 + 1

y = 8 + 1

y = 9

This is a 3 part question, PLEASE HELP ILL GIVE BRAINLY
kaheart [24]

Answer:

Angle of A = 90 degree-62 degree =  28 degree.

Step-by-step explanation:

tan (62) = opposite / adjacent = 10 / a ---> a = 10/tan (62) = 10/ 1.88 = 5.319

cos (62) = a/c --->c = a/cos (62) = 5.319 / 0.47  = 5.3 / 0.47  = 11.3

or another way.

sin (62) = 10 /c  ---> c = 10/ sin (62) = 10 / 0.88 = 11.3

So Angle of A = 28 degree.

a = 5. 3

c =  11.3.

please give me brainliest. I hope it help.
