The measures of two angles in a triangle are 32o and 78o. Which of the following equations could be used to find the measure of the third angle, x? (the ¨o¨ is a degree symbol)

180−32+78=x

180−32=x−78

180−(32+782÷2)=x

32+78+x=180

32+78+x=180

Step-by-step explanation:

All triangle angles add up to 180, so add 78 and 32 then subtract it from 180 to get x, which in another form is 32+78+x=180.

32 + 78 + x = 180

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180, that is

32 + 78 + x = 180

i think it is 18

step-by-step explanation:

i believe a. 12x≥120 is the answer
