Question

.. Two angles of a triangle are 35º and 64º. Its third
angle is -
(A) 91°
(B) 101°
(C) 81°
(D) 105°​

Answer 1

Answer:

(C)81°

Step-by-step explanation:

By using angle sum property,

35+64+x(or the third angle)=180°

99+x=180

x=180-99

x=81°

Answer 2

Answer :-

Let the another angle be x.

A/C:-

x + 35 + 64 = 180

➪ x = 180 - 99

➪ x = 81

Therefore, The another angle is 81°
