Answer 1

Answer:

Yes it's almost correct.

Instead, you could write,

Sum of all the angles = 180°

70° + 40° + x = 180°

110° + x = 180°

x = 180° - 110°

x = 70°

Hope it helps ☺☺

Answer 2

ya babe this is correct

but 1 step is sum of all angle is = 180

let x should be used

so angle a + angle b + angle c = 180

therefore 70+40=110

180- 110= 70

so the value of x is = 70
