Answer:
Left up x=34
Left down x=87
Right x=17
Step-by-step explanation:
The picture is the working out.
You draw the reference angle of 45° but clockwise. The exact value of sin(-345°) is 1/√2.
To find the volume, you need to multiply l x w x h
5 x 7 x 10
5 x 7 = 35
35 x 10 = 350
350 is the correct answer
