Find the value of x. Classify the triangle by its angles.
Kobotan [32]

Answer: 88 degrees; acute triangle

Step-by-step explanation:

All angles of a triangle must add up to 180 degrees. Therefore, to find the value of "x", the work must look like this: 43+49=92 --> 180-92=88. This triangle can be classified as an acute triangle since all of its angles are acute (less than 90 degrees).
