16.3401346384 is the square root of 267.
Answer:
x=88, so it is acute.
Step-by-step explanation:
The two known angles are 45 degrees and 47 degrees. We know that in a triangle, the three angles always add up to 180 degrees.
This means that the third angle is 180-(45+47), or 180-92, or 88. So, the third angle is 88 degrees.
Acute triangles are when all the angles are less than 90. Right is when one angle is exactly 90. Obtuse is when one is more than 90. 88, 45, and 47 are all less than 90, so it is an acute triangle.
