What is the value of y?
Fiesta28 [93]

Answer:

y = 126.43

Step-by-step explanation:

Essentially what you have is the Cosine(50)

Cos(50) = adjacent / hypotenuse

adjacent = 122

hypotenuse = ?? = y

Solve

Cos(50) = 122/y         Multiply both sides by y

y*cos(50) = 122         Divide by cos(50)

y = 122 / cos(50)       Find the value of cos(50)

y = 122 / 0.96497     Divide

y = 126.43

Solve for x: x+4(x+4+3x) = 8(8+19)
densk [106]
X + 4( x + 4 + 3x) = 8(8 +19)
x + 4 (4x + 4) = 8(27)
x + 16x + 16 = 216
17x + 16 (-16) = 216 (-16)
17x = 200
17x/17 = 200/17
x = 11.76


x = 11.76 is your answer

hope this helps
