Answer:
∠A=30°
Step-by-step explanation:
let's call the angle at the bottom B and the one next to the 130 C
∠A=3x-6
∠C=180-130= 50°
vertical angles are equal∠B =8x+4
∠A+∠C+∠B=180°
find x:
3x-6+50+8x+4= 180°
11x+48=180°
11x= 132
x=12
find ∠A
∠A=3x-6= 3(12)-6 =30°
Answer:
y = - x +9
Step-by-step explanation:
slope = (9-0)/(0-9) = - 1
line equation : y= mx + c
find c : 9= - 1*0 +c ....... >> c = 9
y = - x +9 ans
