Answer:
45°
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°
60 + x + 87 + x + 57 = 180 add like terms
2x + 204 = 180 subtract 204 from both sides
2x = -24 divide both sides by 2
x = -12
angle A is x + 57 so if we replace A with the value we found
(-12) + 57 = 45°
Answer:
(f - g)(x) = 3x - 7
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
= 4x - 3 - ( x + 4 )
= 4x - 3 - x - 4
= 3x -7
Step-by-step explanation:
sec² x − 2 = 0
sec² x = 2
cos² x = ½
cos x = ±√½
x = π/4, 3π/4, 5π/4, 7π/4
