Answer:
x = 21.44506921
Step-by-step explanation:
Trigonometry
We need to find x or the adjacent
We are given the Opposite ( 10 )
We don't need the hypotenuse
So we use our formula triangles
TOA SOH CAH
Since we don't need the hypotenuse, we look for a formula without ' H ' in it and it is TOA so we use it
Tan = Opposite ÷ Adjacent
We need to find the adjacent so we rearrange the formula into
Adjacent = Opposite ÷ Tan
Adjacent = 10 ÷ tan(25)
Adjacent = 21.44506921
