$\hat{E} + \hat{V} + \hat{W} + \hat{X} = 360 \\ \Leftrightarrow \hat{V} = 360 - \hat{E} - \hat{W} - \hat{X} \\ \Leftrightarrow \hat{V} = 360 - 8x + 12 - 5x + 3 - 5x \\ \Leftrightarrow \hat{V} = - 18x + 375 \\ \hat{X} + \hat{V} = 180 \\ \Leftrightarrow - 18x + 375 + 5x = 180 \\ \Leftrightarrow - 13x = - 195 \\ \Leftrightarrow x = 15\\\Rightarrow \hat{X}=5 \times 15=75°$

What is the value of x?

Oliga [24]

Answer:

x = 14

Step-by-step explanation:

4x + (2x + 6) = 90

6x + 6 = 90

subtract both sides by 6:

6x + 6 - 6 = 90 - 6

6x = 84

divide both sides by 6

6x/6 = 84/6

x = 14

double check:

4*14 + (2*14 + 6) = 90

56 + 28 + 6 = 90

Have a nice day!
