Adding up the whole hours first is 5+6+4 = 15. Adding the fractions is 1/2 + 3/4 + 1/2 is 1 3/4
This is 16 3/4 (answer c)
Answer:
The correct question is:
Simplify by referring to the appropriate triangle or trigonometric identity. (Use symbolic notation and fractions where needed.) cot[sin−1(1/2)]
Answer:
cot(sin^(-1)1/2) = 1/√3
Step-by-step explanation:
To simplify cot(sin^(-1)1/2)
Let a = sin^(-1)1/2
Then sin(a) = 1/2
and
cot(sin^(-1)1/2) = cot(a)
Since
sin(a) = 1/2
a = π/6
cot(a) = 1/tan(a) = sin(a)/cos(a)
But cos(a) = cos(π/6) = (√3)/2
So
cot(π/6) = sin(π/6)/cos(π/6)
= (1/2)/((√3)/2)
= (1×2)/((√3)×2)
= 2/2√3
= 1/√3

Answer:
m∠T = 45°
Step-by-step explanation:
The sum of angles in a triangle is 180°.
∠S + ∠T + ∠U = 180°
2x + 10 + 3x - 9 + 6x - 19 = 180
11x - 18 = 180
11x = 180 + 18
= 198
x = 198 ÷ 11
x = 18
m∠T = 3x - 9
= 3(18) - 9
= 54 - 9
m∠T = 45°
