Answer:
x ≈ 1.4
Step-by-step explanation:
Using the sine ratio in the right triangle
sin50° =
=
=
( multiply both sides by 1.8 )
1.8 × sin50° = x , then
x ≈ 1.4 ( to the nearest tenth )
162 is not a perfect square therefore you have to find the largest perfect square that can go into 162 which would be 81.
Okay, so we multiply..
And we know that a week = 7 days..
So..
2 * 2/3 * 7 = ???
We change the 2 into 2/1
THEN we multiply..
2/1 * 2/3 = 4/3
Then we change the 7 into 1/7.. ( Which is still a whole )
Then multiply again..
4/3 * 1/7 = 4/21
You can correct me if I'm wrong...
I hope this helps you!
