Uh is there a picture cuz we can't know what's a vetex angle if we don't see a pic
99,999,999 + (-4) is basically 99,999,999 - 4
99,999,999 - 4 = 99,999,995
Answer: The speed is 22.2 mi/hr and woman is 8° north relative to the surface of the water.
Step-by-step explanation:
Since we have given that
Speed at which woman walks due west = 3 mi/hr
Speed at which ship moving due north = 22 mi/hr
Now it forms "Pythagorus theorem":
So, it becomes,

And the direction of the woman relative to the surface of the water is given by

Hence, the speed is 22.2 mi/hr and woman is 8° north relative to the surface of the water.
The ones with a square in a picture is a 90 degree angle the rest are a 180
Reduce the expressions, if possible by cancelling the common factors.
Exact form: 22/9
Decimal form: 2.4
Mixed Number form: 2 2/9
