i. Two angle of a triangle are 30' and 80° and find third angle.
Find value of x
B 280​

Answer 1

Step-by-step explanation:

The sum of the interior angles of a triangle are equal to 180°.To find the third angle of a triangle when the other two angles are known subtract the number of degrees in the other two angles from 180° .

Therefore180°

−30 ° −80 °

=70 °

Answer 2

answer:

there are two angle of a triangle is 30° and 80° then the third angle will be 70°

step-by-step explanation:

because sum of two angles is equal to 180°,

so , first angle is 30° + second angle 80° + third angle..? = 180°

30° + 80° + third angle= 180°

110 + third angle= 180°

third angle= 180° - 110°

third angle = 70°

hence the third angle should be 70°
