Question

Please explain step by step

Answer 1

Step-by-step explanation:

Sum of all angle in triangle = 180

x + 2x + 3x = 180

6x = 180

x = 180/6

x = 30

Answer 2

Answer:

${x}^{o} = {30}^{o}$

Step-by-step explanation:

Hint :

Sum of angles in triangle = 180°

Solution :

${x}^{o} + {2x}^{o} + {3x}^{o} = {180}^{o} \\ {6x}^{o} = {180}^{o} \\ {x}^{o} = \frac{ {180}^{o} }{ 6 } \\ {x}^{o} = {30}^{o}$

${2x}^{o} = {30}^{o} \times 2 \\ = {60}^{o}$

${3x}^{o} = {30}^{o} - 3 \\ {90}^{o}$
