ANSWER THIS QUESTION​

Answer 1

as we know that the sum of angles of a triangle is 180 

here,

angle A + angle B =110

angle A + angle C= 135

now,

180 = (angle A + angle B) - angle A + (angle A + angle C)

180= 110 + 135 - angle A 

180 - 110 - 135 = angle A 

180-245 = - angle A

- 65 = - angle A

65= angle A 

 i hope this will help you

Answer 2

Answer:

∠A = 65°

Step-by-step explanation:

Given:

∠A + ∠B = 110

∠A + ∠C = 135

Adding these together gives

( ∠A + ∠B ) + ( ∠A + ∠C ) = 110 + 135 = 245

=> ∠A + ( ∠B + ∠A + ∠C ) = 245

=> ∠A + 180 = 245                   [ since sum of angles in triangle is 180° ]

=> ∠A = 245 - 180 = 65
