Answer:
Step-by-step explanation:
is the expression given to be solved.
First of all let us have a look at <u>3 formulas</u>:
Both the formula can be applied to the expression() during the first step while solving it.
<u>Applying formula (1):</u>
Comparing the terms of with
So, is reduced to
<u>Applying formula (2):</u>
Comparing the terms of with
So, is reduced to .
So, the answers can be:
ANSWER: ∠T = 32.4°
Remember the formula for the basic trig functions: SOH CAH TOA
Since you want to find cosine for <T, you need the adjacent side length as well as the hypotenuse's length which can be found using the Pythagoras's Theorem with <em>a </em> and <em>b</em> being the side lengths and <em>c</em> being the hypotenuse.
Using the theorem, we get c=37
Now use the cosine formula to get <T = 12/37 to get the final answer.
It is only 1 proportion, and it is 1 problem.
10 8
---- = ---
X 4
1). It is 8x=40
2). Divide both sides
by 8
3). X=5
