Carol measures the hypotenuse of a right triangle and records it as 5x^2-12. She then measures the short leg and records it as 7x+12. How much longer is the hypotenuse than the leg?

In the triangles, bc =de and ac fe. if the mzc is greater than the mze, then ab isdfelth

Lola says these two expressions have the same value. expression a expression b which explains whether lola is correct?

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 > ?
