How do i do question 3 a b c
viva [34]

Answer:

a) 240°

b) 30°

c) 225°

Step-by-step explanation:

To solve these equations you have to use the inverse of the given trigonometric functions. The inverse of <em>sin</em> is <em>arcsin</em>, and the inverse of <em>tan </em>is <em>arctan. </em>Instead of giving an angle, what is its sine?, the question is: given a sine,  what is the angle?.

a)

sin(θ) = -√3/2

θ = arcsin(-√3/2)

θ = -60°

Given the periodicity of sine function, sin(-60°) is equivalent to sin(240°) (-60+180) and sin(300°) (-60+360).

b)

tan(θ) = 1/√3

θ = arctan(1/√3)

θ = 30°

c)

csc means cosecant, by definition:

csc(θ) = 1/sin(θ)

csc(θ) = -√2

1/sin(θ) = -√2

sin(θ) = -1/√2

θ = arcsin(-1/√2)

θ = -45° or 360-45 = 315° or 180+45 = 225°

The angle of depression from the hot-air
BlackZzzverrR [31]

Answer:

3497.47 feet

I think it's the answer because when you look where I've drawn...that's where the angle of depression is and 6600 is the hypotenuse, so you use the sine method where you have opposite over hypotenuse

\sin(32 = opposite \6600)

and you'll get your answer as 3497.47

ms. jeffers is splitting $775 among her three sons. of the oldest gets twice as much as the youngest and the middle son gets $35
Angelina_Jolie [31]

The oldest son will get $370, the middle will get $220 and the youngest will get $185.

Step-by-step explanation:

Given,

Total amount to be split = $775

Let,

Oldest son's share = x

Middle son's share = y

Youngest son's share = z

According to given statement;

x+y+z=775     Eqn 1

the oldest gets twice as much as the youngest

x = 2z             Eqn 2

the middle son gets $35 more than the youngest

y = z+35         Eqn 3

Putting value of x and y from Eqn 2 and 3 in Eqn 1

2z+(z+35)+z=775\\2z+z+35+z=775\\4z=775-35\\4z=740\\

Dividing both sides by 4

\frac{4z}{4}=\frac{740}{4}\\z=185

Putting z=185 in Eqn 2

x=2(185)\\x=370

Putting z=185 in Eqn 3

y=185+35\\y=220

The oldest son will get $370, the middle will get $220 and the youngest will get $185.
