Answer:
(15, 8, 7 )
Step-by-step explanation:
x - y + z = 14 → (1)
y + z = 15 → (2)
z = 7 ← value of z is given
Substitute z = 7 into (2)
y + 7 = 15 ( subtract 7 from both sides )
y = 8
Substitute y = 8, z = 7 into (1)
x - 8 + 7 = 14
x - 1 = 14 ( add 1 to both sides )
x = 15
solution is (15, 8, 7 )
Answer:
cos x = 8/f.
Step-by-step explanation:
We can use the identity :
tan x = sin x / cos x.
Substituting:
e/8 = e/f / cos x
e/8 * cos x = e/f
cos x = e/f * 8/e
cos x = 8e / fe
cos x = 8/f.
