A triangle has angles that measure 54.6 and 17.8 . What equation can be used to find the value of the third angle in the triangle

180=54,6+17,8+x(the third angle)

Step-by-step explanation:

The three angles in a triangle counted together always give 180 degrees. Therefore, you can use simple equation, in which you subtract the values of the two known angles from 180 (degrees) and the final number will be the value of thethird angle. In this case, it's

180-54,6-17,8=x

107,6=x

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
