If tsr = 84 what is the value of x? SQ bisects TSR RSQ= 3x-9

dsp73

We know that
∠ TSR = 84°

if SQ bisects ∠ TSR
then
∠ RSQ = ∠ TSR/2
so
∠ RSQ = (1/2)*84°----- 42°
∠ RSQ = 3x-9
3x-9=42-------> 3x=42+9------> 3x=51-----> x=51/3-----> x=17°

the answer is
x=17°

Answer:

y ≈ 5.2

Step-by-step explanation:

∠ F = 180° - (42 + 48)° ← sum of angles in a triangle

∠ F = 180° - 90° = 90°

Thus Δ DEF is right at F

Using the sine ratio in the right triangle

sin48° = $\frac{opposite}{hypotenuse}$ = $\frac{DF}{DE}$ = $\frac{y}{7}$ ( multiply both sides by 7 )

7 × sin48° = y , then

y ≈ 5.2 ( to the nearest tenth )
