Which expression converts 45 degree to radians

see explanation

Step-by-step explanation:

To convert from degrees to radians use

radians = degree measure ×

For 45°, then

radian measure = 45 × =

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

this is answer of 144 cubic meters
