Answer:
The values of x that satisfy the given equation are:
x1 = 1.183 + nπ
x2 = -1.183 + nπ
Step-by-step explanation:
Given tan²x - sin²x/sin²x = 5
Simplifying this, we have
tan²x - 1 = 5
Adding 1 to both sides, we have
tan²x = 6
Because tan²x = (tanx)², we can write as
(tanx)² = 6
Taking square roots of both sides, we have.
tanx = ±√6
x = arctan(±√6) + nπ
≈ 1.183 + nπ or -1.183 + nπ
Answer:
X = 18
Y = 18
Step-by-step explanation:
first make two equation like
x + y = 36
1180x + 125y = 23490
from equation one we have
y = 36- x
put in second equation
1180x + 125 (36-x) = 23490
1180x + 4500-125x = 23490
1055x = 23490-4500
x = 18990/1055
x = 18
put this x value in equation 1 to find y value
18+ y = 36
y = 36-18
y = 18
