Question

Can you please find x

Answer 1

Answer:

x = 27

Step-by-step explanation:

$30 \degree = \frac{1}{2} \{(5x + 10) \degree - (3x + 4) \degree \} \\ 30 \degree \times 2= \{(2x + 6) \degree \} \\ 60 \degree = (2x + 6) \degree \\ 60 = 2x + 6 \\ 2x = 60 - 6 \\ 2x = 54 \\ x = \frac{54}{2} \\ \huge \red { \boxed{x = 27}}$
