The problem
You might be given two inside angles (in levels) of a triangle.
Write a operate to return the third.
Be aware: solely optimistic integers will likely be examined.
The answer in Golang
Possibility 1:
package deal answer
func OtherAngle(a int, b int) int {
return 180-a-b
}
Possibility 2:
package deal answer
func OtherAngle(a int, b int) int {
if a + b > 180{
return -1
}
return 180 - a - b
}
Possibility 3:
package deal answer
import "math"
func OtherAngle(a int, b int) int {
const fullNumber = 180
var thirdNumber int = int(float64(fullNumber) - (math.Abs(float64(a)) + math.Abs(float64(b))))
return thirdNumber
}
