Answer:
Step-by-step explanation:
So we have the equation:
First, subtract 8x from both sides:
Add 39 to both sides:
Divide both sides by 4:
And we're done!
Answer:
Step-by-step explanation:
Let the hypotenuse of the smaller triangle be h units.
Then; from the Pythagoras Theorem.
From the smaller triangle;
and
From the second triangle, let the other other shorter leg of the second triangle be s units.
Then;
and
We now use the double angle property;
we plug in the values to obtain;
Good evening!
We can solve this problem noting that we have a right-angled triangle. You can see in the attachment a draft of the problem.
We want to discover the angle
θ.
Note that the
tangent of the angle gives a information about this angle.
tangent = opposite / adjacent
