Answer:
angle a = 65 degrees
Explanation:
Given:
angle a +b=110
angle c+a=135
We know: Sum of angles in a triangle is 180 degrees.
a+b+c = 180
Find angle c by substituting a+b = 110
110+c = 180, subtract 110 from both sides
c= 70
Find angle a, by substituting c = 70 in c+a = 135
70+a = 135, subtract 70 from both sides
a= 65
