Answer:
836m
Step-by-step explanation:
Answer:
Solution given:
angle : 80°
hypotenuse:y=?
opposite=21
we have
Sin 80=
doing crisscrossed multiplication
we get
y=
<u>y=21.32</u>
Multiply 4.62 by a number that to get an integer.
Such as multiply by 5 is 23.10 so to get rid of 0.1, just multiply by 50 then it becomes 231.
so that means...
4.62 = 231 / 50
or a simple answer would be multiply by 100, then you get 462.
so....
4.62 = 462 / 100
And then simplify, it is divisible by 2 so the answer is 231/50
You are expected to know (-x)*(-x) = x^2 = (x)*(x) for any value of x.
With this in mind, you expect to be looking for squares in answer to your question. You will find them.

2) y² = 16 . . . . . . . 3rd selection
