Question

in a triangle ABC,B=110 find the two triangles​

Answer 1

Answer:

Step-by-step explanation:

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
