Question

2. If the two angles of a traiangle are 30° and 40° respectivly then find the measure of third angle​

Answer 1

Answer:

110°

Step-by-step explanation:

by angle sum property

sum of all angles = 180°

therefore ,

30°+40°+x = 180°

70°+x =180°

x = 110°

Answer 2

Answer:

Measure of two angles of triangle = 30 degree, 40 degree

Let, the third angle be = x

Sum of three angles of triangle = 180 degree

So,

30 + 40 + x = 180

=> 70 + x = 180

=> x = 180 - 70

=> x = 110

Third angle of the triangle = 110 degree

Ans. 110 degree
