Question

(a)In a triangle ABC angle A= 30°and angle B=60° then find the angle c.
(b) subtract: (6x-5y) -(2x-3y)​

Answer 1

hope it helps

pls flow me

Answer 2

Step-by-step explanation:

we know that sum of all angles in a triangle is 180°

so,

angles A +B +C = 180°

so, 30°+60°+C = 180°

= 90° + C = 180°

= c = 180-90

since, C = 90

hence, it's right angled triangle

(ii) (6x-5y) - (2x-3y)

= 6x-5y -2x+3y

= 4x-2y
