Question

In triangle ABC , angle a =angle b + angle c then what is angle a

Answer 1

angle a =90°

this is because measure of one angle of a triangle could not be more than 90° . so the other two angles will be less than 90° ,and they are acute angle.or the total measure of triangle (angle a+ angle b+angle c=180°)

e.g 90°(a)= 45°(b)+45°(c)
45°,45° - acute angle

hope it helped
