Answer:
x= 20 , y= 10√3
Step-by-step explanation:
This question is clearly a trigonometry question
Please bare in mind :
Cos 60 = 1/2
Sin 60 = √3/2
Tan 60 = √3
Side x is the hypotenuse (h)
Side y is the Opposite (o)
And side with length of 10 is adjacent (a)
To find x, we have a, and we need h
So we use C = a/h
Cos 60 = 10/h
h = 10/Cos 60
h = 10/0.5
h = 20 , x=20
To find y, we can use pythagaros as we found the value of x :
10² + y² = x²
10² + y² = 20²
y² = 20²-10²
y² = 300
y = √300
y= √100×3 y=√100 × √3
y = 10√3
This is our y value
Another way to find y is trigonometry :
We have a and we need o so we use :
T = o/a
Tan 60 = o/10
o = 10×tan 60
o = 10×√3
o = 10√3 , y=10√3
