​

Answer 1

Answer:

plz mark my answer brainliest

Step-by-step explanation:

Let the remaining angle be x

As we know,

X + 65+45=180(sum of angle of triangle)

X=180-110

So, x= 70

Answer 2

Step-by-step explanation:

$\huge \boxed { \red{\bold{Given}}}$

Two angles of the triangle which is given :- 65° and 45°

Sum of all angles of a triangle = 180°

$65 + 45 + x \: = \: 180 \\ 110 + x \: = \: 180 \\ x \: = \: 180 - 110 \\ x \: = \: 70$

Therefore, the third angle is 70°
