Question 20. SQ is an angle bisector. Find the value of x. Please help!! Struggling

Answers

Answer:

The value of x is 6.

Step-by-step explanation:

Given:

∠TSQ = (5x + 3)°

∠RSQ = (10x - 27)°

SQ is the angle bisector of ∠ TSR

To Find:

x = ?

Solution:

Angle Bisector:

A line that splits an angle into two equal angles.

'Bisect' means to divide into two equal parts.

SQ is the angle bisector of ∠ TSR ....Given

∴ \angle TSQ=\angle RSQ

Substituting the values we get

(5x+3)=(10x-27)\n\n10x-5x=27+3\n\n5x=30\n\n\therefore x=(30)/(5)=6\n\therefore x=6

The value of x is 6.
