First, we are going to use the Pythagorean identity:
to rewrite our expression. Solving for
in our Pythagorean identity we get that
, so we can rewrite our expression as follows:
Next, we are going to use the trig identity:
to completely simplify our expression:
We can conclude that
Answer:
a4
Step-by-step explanation:
the answer is "a4" because in algebra when letters are being multiplied by numbers there isn't meant to be a space between the two(i.e. 4x)
hope this helps :) im sorry if it's unclear have a nice day !!
For each triangle sum of it's angles must add to 180°.
We need to check if these angles satisfy that condition:
32°+51°+97°=180°
They do satisfy. Now we check if any angle has value that is not possible.
32° and 51° angles are OK.
97° angle is also OK. It is obtuse angle.
For each angle measures exactly one triangle exists. In this example we have an obtuse-angle triangle.
1/7in=1/14min
14/7in=min
2in=min
the rate is 2 inches per minute.
