Question

two acute angles of a triangle are 65 and 30 find the third angle
​

Answer 1

Answer:

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∘

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

65 + 30 + x = 180

95 + x = 180

x = 180 - 95

x = 85°
