x + 40 + 70 = 180
x + 110 = 180
x + 110 - 110 = 180 - 110
x = 70 degrees

Since the sum of the three angles has to be 180 degrees, in this case, we can write the third angle as 180 - (40 + 70) = 180 - 110 = 70 degrees.

The sum of the measures of the three angles must equal 180 degrees. So subtract the two given angle measures from 180 degrees:
180 - 40 - 70 = 70 degrees

The 3 angles of a triangle always total to 180°
Third angle = 180 - (40 + 70) = 70°

Since the sum of the interior angles of a triangle equal 180 deg, if x is the third angle, then: 180 = x + 45 + 60 180 = x + 105 x = 180 - 105 x = 75 degrees ANSWER

The interior angles of a triangle must always add up to 180 degrees, so your third angle must be 70 degrees because 40+70+70=180.

the measure of the third angle is 70 degrees because the sum is always 180 degrees.
180-70-40=70

The sum of the angles of any triangle is always 180 degrees.
With the 2 angles you're already given, you have 110 degrees so the remaining angle mus be 180-110 or 70 degrees.

The sum of all the angle is always 180 degrees, so you can use that formula to figure out any missing angle of any triangle. In this case it is 40 degrees
