Question

please help me i am begging i will give 20 pts, brain, 5 star and thanks. (if its right.) [must include step by step]

Answer 1

46°

Explanation:

Δ1 = 180 - 130 = 50°

Δ2 = 180 - 50 - 84 = 46°

Answer 2

`\large\boxed{\bf\:\angle \: 2 = 46^(\circ)}`

Explanation:

In the given triangle,

∠1 + ∠2 + 84° = 180° (angle sum property of triangles states that all the 3 angles in a triangle will sum up to 180°)

Here,

∠1

= 180° - 130° (a linear pair makes 180°)

= 50°

So, acoording to the angle sum property of triangles,

∠1 + ∠2 + 84° = 180°

∠2 + 50° + 84° = 180°

∠2 = 180° - (50° + 84°)

∠2 = 180° - 134°

∠2 = 46°
