Question

two angle of a triangle are 40 and 35 respectly what is measure of the third angle​

Answer 1

by the problem

we get two angles of a triangle = 40° & 35°

let the other angle be a

by the angle sum property

a + 40° + 35° = 180°

a + 75° = 180°

a = 180° - 75°

a = 105°

Answer 2

the total sum of all andles in triangle is 180 cm

so, 40+35+ 3rd angle=180 cm

let us assume the third angle to be x

so, 75+x=180

x=180-75

x= 105

hope it helped..good day!
