Question

solve question 11 with step by step process ​

Answer 1

Step-by-step explanation:

Given that the angle of three sides =

∠1, ∠2, ∠3

Now,

angle TQR + ∠2 = 180° ....( straight angle)

=> 104° + 2 = 180°

=> ∠ 2 = 180° -104°

=> ∠2 = 74°

therefore,

∠ 3 + 136° = 180° ....( straight angle)

=> ∠3 = 180°-136°

=> ∠3 = 44°

Now,

according to the property of triangle:

sum of interior angle of triangle = 180°

so,

1+ ∠2 + ∠ 3 = 180°

∠ 1 + 74°+44° = 180°

∠1 + 118° = 180°

∠ 1 = 180°- 118°

∠1 = 62°.

so, 3 angles are as ====>

∠ 1=> 62°

∠ 2 => 74

∠3 => 44°
