Answer:
78
Step-by-step explanation:
Since the two angles at the bottom are congruent, you would the two equations equal to each other. So it would be:
5x-19=2x+11
Once you simplify, you will find that x= 10.
Then you plug in x for both equations, so 5(10)-19= 31 and 2(10)+11= 31
So you add up the sides: 31+31+16= 78
Where ever the line crosses the x axis so if you go on desmos.com and type the equation in you'll find it really easy. it crosses at (-12,0)

Step-by-step explanation:
RS ⊥ bisector of AB Given
AS ≅ BS Definition of ⊥ bisector
∠RSB is a right angle Given
∠RSB = 90° Definition of right angle
∠RSB & ∠RSA form a linear pair Definition of linear pair
∠RSB + ∠RSA = 180 A linear pair = 180°
90° + ∠RSA = 180° Substitution
∠RSA = 90 Subtraction
∠RSB = ∠RSA Substitution
∠RSB ≅ ∠RSA If equal then congruent
RS ≅ RS Reflexive
Δ RAS ≅ ΔRBS SAS
