Step-by-step explanation:
✧
- Set up an equation and solve for x :
⋆ [ Exterior angle is always equal to the sum of two non - adjacent interior angles ]
~Remove the unnecessary brackets
⟶
~Add the like terms : 2x ° & 3x°
⟶
~Move 4x to right hand side and change it's sign
~Similarly move 12 to left hand side and change it's sign
⟶
⟶
⟶
- Now , Substituting the value of x in (4x+9)° [ Exterior angle ]

A^2+B^2=C^2
4^2+B^2=6^2
B^2=36-16
B=4.5
Answer: B and F
Step-by-step explanation:
Solve for the slope.
-5-4/-3-2 this is using the slope formula and the points given. The slope is 9/5. Use this slope to fill in the point slop formula.
The point slope formula is (y-y1)=m(x-x1)
Fill it in and you get your answers.
