The radius of the circle below intersects the unit circle at 6 5 . What is the approximate value of a? U (0.1) 7 T 2. Tu (-1,0) 0 0 (1,0) 32 2. (0, -1) [Not drawn to scale]​

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

a

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
