Answer:
x= 3/8 or 0.375
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
7x+−12=3x+1
Step 2: Subtract 3x from both sides.
7x+−12−3x=3x+1−3x
4x+−12=1
Step 3: Add 1/2 to both sides.
4x+−12+12=1+12
4x=32
Step 4: Divide both sides by 4.
4x4=324
x=38
2. alternate angles I think
3. vertically opposite angles
4. Interior angles
I would say m∠TBS= 52°
SV=15
m∠TCV=52° as well
this is my best guess
wish I could help more sorry:(
