Question 676463
Well, triangles have a total of 180 degrees (something you should really know), therefore we can construct the following equation: 63+30+x=180 
Combine like terms: 93+x=180 
Subtract 93 from both sides: x = 87 
Thus, the measure of the third angle is 87. 

This triangle is acute, because all of the angle measurements fall under 90 degrees.
