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

Answer:
q=17
Step-by-step explanation:
5q-10=75
add 10 to both sides to cancel out -10 on the left side
5q-10+10=75+10
5q=85
divide both sides by 5 to get rid of the 5 in 5q
5q/5=85/5
resulting in:
q=17

Answer:
z=-2/3y+1
Step-by-step explanation:
Let's solve for z.
3yz+z=−2
Step 1: Factor out variable z.
z(3y+1)=−2
Step 2: Divide both sides by 3y+1.
z(3y+1)
3y+1
=
−2
3y+1
z=
−2
3y+1
Answer:
z=
−2
3y+1
