Question

= 12.40
3. Find the measure of the third angle of triangle whose two angle below
38,102​

Answer 1

Answer:

Third angle is 40 degree angle

Step-by-step explanation:

Total sum of angles of triangle is 180=x+y+z

you can take y=102

and z=38

180=38+102+x

180-38-102=x

180-140=x

40=x

Ans 40 degree angle

Answer 2

Answer:

40⁰

Step-by-step explanation:

We know, sum of all the interior angles of a triangle is 180⁰

Therefore,

38⁰+102⁰+x⁰=180⁰ (x⁰ being the third angle)

x⁰=180⁰-(102⁰+38⁰)

= 40⁰

Hope this helps
