Answer:
b. x = π/2, x = 3π/2
Step-by-step explanation:
The maximum is found where the argument of the cosine function is a multiple of 2π.
2x -π = 2nπ
2x = (2n+1)π . . . . . . . add π
x = (2n+1) · π/2 . . . . . divide by 2
x = {π/2, 3π/2}
Solve for y by simplifying both sides of the equation, then isolating the variable.
y = x^2/2^z - w/2z
Answer:
Angle x= 76
Step-by-step explanation:
angle DIJ = 180-107
=73
angle x =angle DJI =180-31-73
=76
both angles x and DJI are equal because they both intersect with each other.
