Answer:
Only the second equation is an identity
Step-by-step explanation:
<u>Note that </u>
<u>You can confirm it: </u>
<u>Therefore</u>
<h2>
It is not an Identity</h2>
<u>Let's the second one</u>
In this case, we already performed the calculations, so it is true. It is an Identity.
Answer:

Hi!
An obtuse angle is one greater than 90 degrees, a right angle one that is 90, and acute less than 90.
An obtuse triangle is one with one obtuse angle, all the rest being acute. A right triangle is one with one right angle, all the rest acute. And finally, an acute triangle is one with three acute angles.
In this case, the angles measure 83 degrees, 31 degrees, and 66 degrees. All of them are acute angles, as they're all less than 90 degrees.
Therefore, the triangle is an acute triangle.
Hope this helped!
Answer:
4.) Step 2; it should be m∠o + m∠p = 180 degrees (supplementary angles)
Step-by-step explanation:
o and p are supplementary angles, and therefore add up to 180 degrees.
