Question

The angels of a triangle are (x - 40°), (x - 20°) and (x - 10°). Find the value of x​

Answer 1

Answer:

x-40'+x-20'+x-10=180'

3x-70'=180'

3x=180'+70'

3x=250

x=250/3

x=83.33

Step-by-step explanation:

Answer 2

x = 83⅓° or 83.34°

Step-by-step explanation:

We know,

Sum of all the angles = 180°

(x - 40°) + (x - 20°) + (x - 10°) = 180°

=> x - 40° + x - 20° + x - 10° = 180°

=> 3x - 70° = 180°

=> 3x = 180° + 70°

= 250°

=> x = 250°/3

= 83⅓° or 83.34° ans.
