The answer is 2/3 beacuse the 1 and 1/3 would turn into 4/3 and then you would subtract and get 2/3

A tree is leaning at a 5° angle from vertical, making an 85° angle with the ground. When the sun is at a 65° angle of elevation,
Vinvika [58]
D = 25 ft is the length of a shadow. L -  the length of a tree.
Two angles are 85° and 65° and the third is 180° - ( 65° + 85° ) =
= 180° - 150° = 30°.
We will use the Sine Law:
25 / sin 30° = L / sin 65°
25 / 0.5 = L / 0.9063
25 * 0.9063 = 0.5 L
22.6577 = 0.5 L
L = 22.6577 : 0.5
L = 45.3 ft.
Answer: the approximate length of the tree is 45.3 ft.

Plz answer question in screen shot
liberstina [14]

Answer:

tan theta = 2 sqrt(5) /15

Step-by-step explanation:

sin theta = opp / hypotenuse

sin theta = 2/7

We can use the Pythagorean theorem to find the length of the adjacent side

a^2 + b^2 = c^2

2^2 +adj^2 = 7^2

4 + adj^2 = 49

adj ^2 = 49-4

adj^2 = 45

Taking the square root of each side

adj = sqrt(45) = sqrt(9*5) =sqrt(9) sqrt(5) = 3 sqrt(5)

The tan theta = opp/ adj

tan theta = 2 / 3 sqrt(5)

Multiply by sqrt(5) / sqrt(5)

                = 2 sqrt(5) / 3 *5

                 = 2 sqrt(5) /15

3^b=17 exponentials into log form
IRINA_888 [86]
Solve for the real domain

3^b = 17

if  f(x) = g(x) , then ln (f(x)) =  ln (g(x))

ln ( 3^b) = ln (17)

log _{a} (x^b) = b*log _{a} (x)

ln(3^b) = bln(3)

bln(3) = ln (17)

Solve  bln(3) = ln (17)

b =  \frac{ln(17)}{ln(3)}

hope this helps !.
