Question

plz solve me this question

Answer 1

one angle is 35
second angle is 90
third angle is x
35+90+x=180
125 +x=180
x=180-125
=55

Answer 2

here is your solution :-

if it is a right angle triangle then angle 2 will be 90 degree ...
and in the Q it is given that angle 1 = 35 degree
let, angle 3 = x

therefore, x + 35 + 90 = 180 (angle sum property of triangle)

so, x = 180 - 125

therefore angle 3 = 55 degree
