Answer:
it states: a squared + b squared = c squared ( the hypotenuse)
Step-by-step explanation:
The student made the mistake in Step 2.
It should be m∠o + m∠p = 180 (Supplementary angles)
If this is corrected, then, since m∠m + m∠n + m∠o = 180 from Step 1,
we have,
m∠m + m∠n + m∠o = m∠o + m∠p which is Step 3.
Cancelling m∠o both sides, we get,
m∠m + m∠n = m∠p which is Step 4.
Answer:
the answer is D {-5, -13}
It is an acute triangle because none of its angles are equal to (right) or above (obtuse) 90 degrees.
