Answer:
Step-by-step explanation:
β ∈ { 0° , 18° , 180° , 198° }
Answer:
y=12°
x= 20°
Step-by-step explanation:
5y=60
y=60/5=12
3x+60+60=180
3x=180-120=60
x=60/3=20

Answer:
The length of AB is
units
Step-by-step explanation:
The rule of the distance between two points (x1, y1) and (x2, y2) is
∵ The endpoints of AB are (-4, 5) and (2, -7)
→ Let point (-4, 5) be (x1, y1) and point (2, -7) be (x2, y2)
∴ x1 = -4 and y1 = 5
∴ x2 = 2 and y2 = -7
→ Substitute them in the rule above to find the length of AB
∵ 
∴ 
∴ 
∴ The length of AB is
units
