Answer:
if sinx=3/5=P/H
using pythogoras thoeren find B
B²= H²-P²
B²= 25-9
B=4
Tanx = P/B= 3/4
3.
n(S)= 6
n(O) = 3 {1,3,5)
P(O) = n(O)/n(s)= 3/6=1/2

Answer:
width of a river = 45m
Step-by-step explanation:
ration and proportion
let x = width of a river
x 20.9 m
------ = --------
56 m 26 m
x = (20.9 * 56) / 26
x = 45 m
therefore the width of a river is 45 m
Answer:
The base and height of the garden are 4.60 ft and 5.60 ft.
Step-by-step explanation:
The area of the garden is, <em>A</em> = 24 ft².
The base height of the garden are:
base (<em>b</em>) = 6x - 4
height (<em>h</em>) = x + 3
Compute the value of <em>x</em> as follows:

The last equation is a quadratic equation.
Compute the roots of the quadratic equation as follows:

The value of base and height are:

Thus, the base and height of the garden are 4.60 ft and 5.60 ft.

Answer:
StartFraction StartRoot 3 EndRoot Over 3 EndFraction
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
we know that
In the right triangle XYZ
---> adjacent side divided by the hypotenuse
substitute the values

Remember that

so
substitute



step 2
--> opposite side divided by the hypotenuse
substitute the values

Remember that

so


step 3
--> opposite side divided by adjacent side
substitute the values
Simplify

so
StartFraction StartRoot 3 EndRoot Over 3 EndFraction
