Answer:
(x + 7) (x - 3)
Step-by-step explanation:
Find 2 numbers that add to 4 and multiply to -21
(x + 7) (x - 3)
Answer:
It’s the first one
Use trigonometry.
tan30° = perpendicular / base
Here for angle 30° , x is perpendicular while 10 is the base.
tan30° = 1/√3
1/√3 = x/10
x = 10/✓3
By rationalising
x = 10√3/3
