Juan has gained 20 lb. since last year. he now weighs 120 lb. rashod is 15 lb. heavier than diego. if rashod and juan weighed the same amount last year, how much does diego weigh? let j represent juan’s weight last year in pounds, and let d represent diego’s weight in pounds.

a. draw a tape diagram to represent juan’s weight.
b. draw a tape diagram to represent rashod’s weight.
c. draw a tape diagram to represent diego’s weight.
d. what would combining all three tape diagrams look like?
e. write an equation to represent juan’s tape diagram.
f. write an equation to represent rashod’s tape diagram.
g. how can we use the final tape diagram or the equations above to answer the question presented?
h. calculate diego’s weight.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
