One other quick note. Make sure you want to list these with the strongest reducing agent at the top and the weakest at the bottom; otherwise, you need to reverse the order. So Cl2 Br2 I2 becomes I2 Br2 Cl2 ?

A road 1.6 km long rises 400 m. What is the angle of elevation of the road? I don't known which numbers go to which sides. I can do the rest once I can label the triangle. Thanks!
well this is what i did can someone tell me what i did wrong: tanx= 5/2 since diagonals of a parallelogram bisect each other x= 68 and the other angle would be 22 the angles of the rhombus would be 136 and 44 because the diagonals of a rhombus bisect the angles
A rhombus has diagonals of length 4 and 10. Find the angles of the rhombus to the nearest degree. would the angles be 136 and 44?
sorry one more question. so... a road climbs at an 8 degree angle with the horizontal. what is the grade of the road? the answer would be 5?
nevermind my calculator was being stupid. thanks
how did u get the 4?
