Answer:
Volume of the other section of tank B = (A-45)cm³
Step-by-step explanation:
Volume of tank A = Volume of tank B
One section of tank B = 45 cm³
Hence volume of the other section of tank B = (A-45)cm³
Place the middle part of the protractor (where the lines intersect) on the vertex of the angle, then just look at the number the other arrow’s pointing!
Answer: A. x + (4x - 85) = 90
In this case, the two angles are complementary. This means they add up to 90°. Therefore, the equation is x + (4x - 85) = 90.
