Cos 28 = 18/ y
so
y = 18 / cos 28
y = 18 /.8829
y = 20.4
Answer:
The answer is
<h2>135°</h2>
Step-by-step explanation:
In order to convert a value from radians to degrees we multiply the value by 
So from the question the value to be converted into degrees is
<h3>

</h3>
<u>Converting into degrees we have</u>
<h3>

</h3>
<u>Reduce the expression with π</u>
That's
<h3>

</h3>
We have the final answer as
<h3>135°</h3>
Hope this helps you
Solve for R by simplifying both sides of the equation, the isolating the variable.
R^2h=-r^2+v
-3x + 18 = 7x
3x + (-3x) + 18= 7x + 3x
18 = 10x
18 10x
— = —
10 10
1.8 = x
