Answer:

Tan (240º) = Tan (60º) = 1.73205

Tan (200º) = Tan (20º) = 0.36397

Step-by-step explanation:

Trigonometrical functions are periodical.

Tangent have periods of 180º (π in Radian scale)

So:

240º = 180º + 60º = π + 60º

200º = 180º + 20 = π + 20º

As Cycle property for tangent:

Tan (π + x) = Tan (x)

So in our exercise:

Tan (240º) = Tan (180º + 60º) = Tan (π + 60º) = Tan (60º) = 1.73205

Tan (200º) = Tan (180º + 20º) = Tan (π + 20º) = Tan (20º) = 0.36397

A 4 meter ladder leans against a house forming a
Ket [755]

Answer:

2.meters

Step-by-step explanation:

Lenght of ladder = 4 m

θ = 30°

To obtain h;

Using Pythagoras rule :

Sinθ = opposite / hypotenus

Hypotenus = 4 ; opposite = h

Sin 30 = h / 4

0.5 = h / 4

h = 0.5 * 4

h = 2 m

Hence, distance between th efoot of ladder and the base of the wall is 2 m

In a pen of goats and chickens, there are 40 heads and 150 feet. How many goats and chickens are in the pen?
s2008m [1.1K]

Hey there!!

A chicken has 1 head and 2 feet . A goat has 1 head and 4 feet

For heads, total = 40

Let us take the number of chickens as ' x ' and goats as ' y '

x + y = 40 ------------- ( 1 )

2x + 4y = 150 ----------- ( 2 )

Multiply the first equation with 2

2x + 2y = 80

2x + 4y = 150

Subtract the first equation from the first

2y = 70

y = 35

Number of goats = 35

substitute this in other equation

x + y = 40

x + 35 = 40

x = 5

Number of chickens are 4

Hope it helps!

Explain prime factorization
kozerog [31]
Prime factorization is when a number can only be multiplied by 1 so 2 is a prime number because nothing times it self equals 2 or nothing but 1 ×2 is 2 prime factorization is just using prime numbers to break down bigger number like 50 5 and 10 and break down the 10 2 and 5
