<em>Note: I am assuming we have to determine the angle 'Ф'.</em>
Answer:
The value of Ф = 22.6°
Step-by-step explanation:
Given
hypotenuse = 13
To determine:
Angle = Ф = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
so substituting adjacent = 12, hypotenuse = 13 in the equation
cos Ф = adjacent / hypotenuse
cos Ф = 12 / 13
Ф = arccos (12/13)
Ф = 22.6°
Therefore, the value of Ф = 22.6°
3km = 3000m
Total = 3000 + 800 + 3000 = 6800m

S--------T--------U
ST = T U
SU = 10
ST + TU = SU
3x + 7x = 10
10x = 10
x = 10/10
x = 1
So, what do you think happens next?
ST = 3x
Let x = 1
ST = 3(1)
ST = 3
I hope this helps.
