Question

the degree measures of the angles of triangle ABC are represented by x , 3x , and 5x-54
Find the value of x

Answer 1

how would you solve this?

Answer 2

\(\bf x^o+(3x)^o+(5x-54)^o = \color{blue}{180}^o\quad ? \)

Answer 3

x+3x+5x-54 = 180
add 54 on both sides of the equation
x+3x+5x-54+54 = 180 + 54
by adding all the x's our equation becomes
9x = 234

divide both sides by 9... do the rest of calculation
