Using Pythagoras theorem

<u>Question 1</u>
Now, cosecant = 1/sin
Therefore:

<u>Question 2</u>
Now, secant = 1/cos
Therefore:

Answer:
y=5 x=3
Step-by-step explanation:
x-y=-2 move the y over to isolate x
x=-2+y Now plug that in for x in the first equation
2(-2+y)-y=1 Distribute
-4+y=1 Add 4 on both sides
y=5
x-5=-2
x=3
3554 by 10 = 355.4
4678 by 40 = 116.95
