A=3B
4.35A+5.40B=780.95
Substitute 3B into A for the second equation:
4.35(3B)+5.40B=780.90
13.05B+5.40B=780.90
18.45B=780.90
B=42.33
Plug into equation 1:
A=3B
A=3(42.33)
A=126.98
Answer:
∠a + ∠b + ∠c + ∠d = 360°
Step-by-step explanation:
∠a + ∠c = 180°
∠b + ∠d = 180°
Therefore, 180 + 180 = 360°
Answer:
The answer is 22.
Step-by-step explanation:
Just well use a calculator. If you don't have that then use PEMDAS. Hope it helps.
