Question

Please tell me only the question number (e) with step by step explanation. please ​

Answer 1

Answer:

sum of measures of angles of any triangle is 180°

1) 45+65=110 i.e. 180-110=70°

2) 120+30=150 then 180-150=30°

and now you find remaining

Answer 2

answer

angle A = angle B =angle C - (1)

angle A + angle B+ angle C = 180 (angle sum property)

by equation 1

then

3 angle A = 180

angle A = 60

so

angle B = 60

angle C = 60
