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 ]

Answer:
x = (ab - ac )/c
Step-by-step explanation:
x/a = b/c - 1 Multiply through by ac:
cx = ab - ac Divide both sides by c:
x = (ab - ac )/c.
To answer this question, you need to have an idea about how to handle trigonometric equations, sin, cos and tan
Amy looks up to the 8-foot basketball
8 feet - 5.9 feet = 2.1
= 2.1 inverse tan (2.1 / 22)
= 5.4526
Elevation to the nearest tenth = 5.5 feet
