Answer 2

$\large {\rm {\purple {\underbrace {\pink {Question}}}}}$

If the measures of the three angles of a triangle are (x+20), (x+30) and (3x-10). What is the value of x ?

$\large {\rm {\purple {\underbrace {\pink {Answer}}}}}$

x + 20 + x + 30 + 3x - 10 = 180

5x = 180 - 40

5x = 140

x = $\large \frac{140}{5}$

x = 28
