Answer:
y= 8
x=12
Explanation:
In this question we will be doing trigonometry (SOH=sine CAH= cosine TOA=tangent) (SIN=sine COS= cosine TAN=tangent)
Find value of y
1. First, we label the triangle the side opposite the 90degrees is called hypotenuse(h) the side opposite 60 degrees is called opposite (o) the remaining side is called the adjacent (a) (4
)
2. From this we can see to find the value of y we need the hypotenuse (h) which is labeled as y and the adjacent (a) which is labelled as 4
3. Therefore we use cosine equation. We subsite the values in and rearrange to get y on it is own and then find the value of y.
cos(angle)=
cos(60)=
y=
y= 8
Find value of x
1. First, we label the triangle the side opposite the 90degrees is called hypotenuse(h) the side opposite 60 degrees is called opposite (o) the remaining side is called the adjacent (a) (4
)
2. From this we can see to find the value of x we need the opposite (o) which is labeled as x and the adjacent (a) which is labelled as 4
3. Therefore we use the tangent equation. We substitute the values in and rearrange to get x on its own and then find the value of x
tan(angle)=
tan (60)=
4
x tan(60)= x
x= 12
