The equation (tanx-1) (secx-1) = 0 with<span> the interval 0≤ x ≤ 2π.
Set each factor to zero, that is
tan x - 1 = 0
secx - 1 = 0
x for tan are </span>
/2, 3
/2, 5
/2
x for sec are 0 and 2
Because they are two different organisms
Answer:
∠AMB = 54°
Step-by-step explanation:
2x + (x + 9) = 90°
3x + 9° = 90°
3x = 81°
x = 27°
∠AMB = 2x = 54°
