Answer:
x = 8.66
y = 10
Step-by-step explanation:
Okay first of all write out sin cos tan. SOH-CAH-TOA
Solve for x : Reference angle is 60. x is the opposite angle. 5 is adjacent. We can conclude that we need to use TAN since it deals with opposite and adjacent. Now write out the equation. tan(60) = x/5.
To get x alone multiply both sides by 5 so we have tan(60)*5 = x
That would be equal to 8.66. Make sure to use degree and not radiant when using calculator.
Solve for y. Ref angle : 60, Adjacent is 5 and y is hypotenuse. We can conclude we need to use Cos.
cos(60) = 5/y. If the variable is in the denominator we can just flip places of y and cos(60). We are left with y = 5/cos(60). Now use a calculator for this and use degree. We will get the answer as 10.
