Question

What is the m 52 40 45 54

Answer 1

Answer:

○ $\displaystyle 54°$

Step-by-step explanation:

Use the Triangular Interior Angles Theorem to figure this out:

180° = [3x]° + [2x]° + [5x]°

$\displaystyle \frac{180°}{10°} = \frac{[10x]°}{10°} \\ \\ 18 = x$

Plug this back into the m∠L to get 54°.
