Question

50. The three angles of a triangle are:
Model Test Paper 12
(5x + 6)", (3x - 3)º and (x - 3)º.
Then x = ?
(a) 30°
(b) 40°
(c) 20°
(d) 10°​

Answer 1

Answer:

(c) 20

Step-by-step explanation:

Sum of angles in a triangle always adds up to be 180.

If we add the angles 5x+6 + 3x - 3 + x - 3 = 9x

so 9x= 180

x= 20

Answer 2

Answer:

Hi There !!

x = 20°

Step-by-step explanation:

(5x+6 )° + (3x-3)° + (x-3)° = 180 ° (Angle Sum Property of a triangle)

9x° = 180°

x = 20°

Hope it helps you !!
