Question

in triangle abc angle A + Angle B equal to 110 but angle C + angle equal to 135 degree find angle A​

Answer 1

so, we can use the angle sum property,

and it says that , sum of the angles in a triangle = 180 degree

= angle  A + B + C = 180 DEGREE

the value of C is 135

and b = 110

so, we can make up a equation that a+b+c=180 degree

= a is the variable here and hence a= 135 - 110 [ C - B]

= A = 25 degrees

check if needed by adding all the angles and you are going to going to get the sum as 180 degrees
