Question

If the angles of a triangle are 2x, x + 30° and 2x + 5°, then the value of 'x' is ​

Answer 1

Answer:

29

Step-by-step explanation:

2x+x+30+2x+5 = 180 (angle sum property)

5x+35=180

5x = 180-35 = 145

5x = 145

x = 145÷5

x = 29

Answer 2

Answer:

$2x + x + 30 + 2x + 5 = 180 \: angle \: sum property \\ 5x + 35 = 180 \\ 5x = 180 - 35 \\ 5x = 145 \\ x = \frac{145}{5} \\ x = 29$
