Due to the Triangle Angle Sum Theorem, we know that the sum of the interior angles of a triangle is 180 degrees.
90 + 2x - 2 + x + 5 = 180 degrees.
Combine like terms.
3x + 93 = 180
Subtract 93 from both sides.
3x = 87
Divide both sides by 3
x = 29
2- 54:81, 54/81
3- 0:101, 0/101
4- 13.5:43.8, 13.5/43.8
The answer is 3: 3+5+8=5+8+3
Answer:
8.1 gallons of gas
Step-by-step explanation:
240/9=216/x
simplify 240/9 into 80/3,
80/3=216/x
cross product
3*216=80*x
648=80x
x=648/80
x=8.1
