There are 3.45 meters in 345cm
Distribute the 2 then do your loop.
5^3 = 2x+16
Then you can solve for x.
Angle 1=180-90-48 =42
Angle 2=180-42 =138
Angle 3= angle 1
Angle 4= angle 2
Angle 5 = 180-72-42=66
Answer:
Step-by-step explanation:
since arc BC is 2 time the angle of A , then
2(9x +12) = 21x +3
18x +24 = 21x + 3
21 = 3x
7 = x
x = 7
∠BAC = 9(7) +12
∠BAC = 63 +12
∠BAC = 75°
