Use the 3 trig ratios to find each unknown side length. Round all answers to 1 decimal

Note: You missed to add some of the details of the question.

Hence, I am solving your concept based on an assumed graph which I have attached. It would anyways clear your concept.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the right angled-triangle ABC as shown in the attached diagram

From the triangle:

Ф= ∠C = 30°

AB = 6 units

BC = y

tan Ф = opp ÷ adjacent

The opposite of ∠C = 30° is the length '6'.

The adjacent of ∠C = 30° is the length 'y'.

As Ф= ∠C = 30°

tan Ф = opp ÷ adjacent

tan 30 = 5 ÷ y

1 ÷ √3 = 5 ÷ y

y = 8.7 units

Therefore, the length of the unknown side length 'y' is 8.7 units.

A plant grows 10 cm each week. The plant is 60 cm now.how many weeks will it take to reach 1 meter

Whitepunk [10]

Answer:

Step-by-step explanation:

We know 100 centimeters = 1 meter.

We know the plant grows 10 cm in 1 week.

100 - 60 = 40.

40 cm remaining / 10 cm per week = 4 weeks.

4.) solve for f(g(2))

Westkost [7]

Answer:

$f(g(2))=10$

Step-by-step explanation:

We have the two functions: $f(x)=3x-5$ and $g(x)=2+\frac{6}{x}$ .

We want to find $f(g(2))$ .

So, let's use the second function to find $g(2)$ first:

$g(2)=2+\frac{6}{2}$

Divide:

$g(2)=2+3$

Add:

$g(2)=5$

Therefore, our expression is the same to $f(g(2))=f(5)$ .

Now, we can substitute 5 for f(x). This yields:

$f(5)=3(5)-5$

Multiply:

$f(5)=15-5$

Subtract:

$f(5)=10$

So:

$f(g(2))=10$

And we're done!
