Question

(3) In the measure of two
angles of a triangle are 30°
and 80°, then the measure
of third angle will be-​

Answer 1

Answer:

Step-by-step explanation :Let x be the third (unknown) angle of given triangle with two known angles 30∘ & 80∘

Since, the sum of all interior angles in a triangle is 180∘ hence we have

x+ 30∘+80∘ =180∘

x+110∘=180∘

x=180∘ − 110∘

x=70∘
