It’s unsolvable with out more context. What’s the rest of the problem.
Answer:
The value of x is 16
Step-by-step explanation:
The angle Bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle
In Δ QPR
∵ QS is the angle bisector
∵ PR is the opposite side
→ By using the rule above
∴
= 
∵ PS = x and PQ = 30
∵ PR = 40
∵ RS = PR - PS
∴ RS = 40 - x
∵ RS = 40 - x and RQ = 45
→ Substitute them in the rule above
∴
= 
→ By using the cross multiplication
∵ x × 45 = 30 × (40 - x)
∴ 45x = 30(40) - 30(x)
∴ 45x = 1200 - 30x
→ Add 30x to both sides
∵ 45x + 30x = 1200 - 30x + 30x
∴ 75x = 1200
→ Divide both sides by 75
∴ x = 16
∴ The value of x is 16
This is the construction of a perpendicular line to the given line AB using a point F, which does'not lies on the line AB.
The first two steps are constructed. We have to give the next two steps to complete the construction.
Step 3: Using the same radius A and B as centers, draw two arcs below the line AB.
Step 4: The two arcs will intersect at a point. Name that point as 'X'. Join 'F' and 'X'.
Thus, FX is the required perpendicular to the line AB from point 'F'.
The answer is x=3. HOPE THIS HELPS!!!!!!!!!!!!!
