SV is an angle bisector of ∠RST. If m∠RSV = (2x + 8)° and m∠RST = (6x − 26)°, find x.

saul85 [17]

Answer:

x = 21

Step-by-step explanation:

Given that SV is the angle bisector of ∠RST, then

∠RSV = ∠TSV, thus

∠RSV + ∠TSV = ∠RST ← substitute values

2x + 8 + 2x + 8 = 6x - 26, that is

4x + 16 = 6x - 26 ( subtract 6x from both sides )

- 2x + 16 = - 26 ( subtract 16 from both sides )

- 2x = - 42 ( divide both sides by - 2 )

x = 21

Is the point 3/5 and 4/5 corresponds to an angle in the unit circle what is the csc

Mariulka [41]

<u>Answer:</u>

csc = 5/4

<u>Step-by-step explanation:</u>

Assuming that the two given points 3/5 and 4/5 are the two sides of a triangle and a right angle 0 with legs x and y and z as its hypotenuse.

Then using Pythagoras Theorem:

$z^2=x^2+y^2$

$z^2=(\frac{3}{5} )^2+(\frac{4}{5} )^2$

$z^2 = \frac{9}{25} + \frac{16}{25}$

$z^2=\frac{25}{25}$

$z^2=1$

Taking square root on both the sides:

$z=1$

Now, $sin\alpha=\frac{4}{5}$

and we know that $csc = \frac{1}{sin\alpha }$

Therefore, csc = 5/4.

The height of a tree increases by 60% each year. When planted the tree was 40cm tall. How tall will the tree be in 5 years time.

Vikentia [17]

Answer:

≈419.4 cm.

Step-by-step explanation:

To solve this problem, you will need to set up an exponential graph as shown:

y= 40 · $(1.6)^{x}$

The 40 represents the initial height of the tree, while (1.6) represents the annual growth rate. 'x' represents the amount of years elapsed.

We can simply solve this by substituting 5 for x:

y= 40· $(1.6)^{5}$

y ≈ 419.4 cm.
