First calculate the missing angle
. By knowing all angles in triangle have a sum of 180°.
Now we required to use angle functions in a right triangle. The cosine of
is equal to the relation of side
and hypotenuse
.
Now we solve this for hypotenuse.
Now put in the numbers.
So we know the length of hypotenuse and length of side
therefore side
can be calculated using Pythagorean theorem:
.
Solve for side
.
So there you go. If you have any questions feel free to ask.

The equation for a volume of a cube is V=a^3 and since all the sides are the same the equation would be V=(x+3)^3
Answer: 55 should just be a part of the data. I don't know if this is what you are asking.
Step-by-step explanation:
Answer:
Stephanie needs 220ft² of more soil to cover the rest of her yard.
Step-by-step explanation:
First add the bags she already has:125ft²+65ft²+<em>x</em>=410ft² --> 190ft²+<em>x</em>=410ft²
Second use the subtraction property of equality: 190ft²-190ft²+<em>x</em>=410ft²-190ft² ---> <em>x</em>=220ft²
F(x) = x + 2
when x = 1, f(1) = 1 + 2 = 3
Therefore range for x ≠ 1 is y ≠ 3.
