Question

Solve for x. Can someone help me fast!

Answer 1

Answer:

$\displaystyle 55° = x$

Step-by-step explanation:

Angles B and C form a straight angle, so you set both expressions equal to 180°:

180° = (2x + 15)° + x°

180° = 15° + [3x]°

- 15° - 15°

____________

$\displaystyle \frac{165°}{3°} = \frac{[3x]°}{3°} \\ \\ 55° = x$
