Question

in a triangle, if two angles measure 30 degree and 110 degree find the third angle​

Answer 1

Answer:

40 degree

Step-by-step explanation:

Here , we have given

in a triangle, two angles measured 30 degree and 110 degree

then ,

30 degree + 110 degree = 140 degree

according to angle sum property of a triangle i. e; the sum of three angles of a triangle is 180 degree.

so ,here 180 degree - 140 degree = 40 degree.

therefore , the third angle is 40 degree .

I hope it is helpful for u .

Answer 2

Step-by-step explanation:

Measure of one angle=30 degree

Measure of another angle = 110 degree

Measure of third angle=x

Therefore sum of all in triangle is equal to 180°

so,30+110+x=180°

140+x=180°

x=180-140

x=40°

Measure of third angle is 40°
