Answer:
E is equal to 20 and F is equal to 50. 20(E)+50(F)=70
Answer:
[tex] m\angle E = 20\degree \\
m\angle F = 50\degree [/tex]
Step-by-step explanation:
Let the common multiplier of the given ratios be x.
[tex]\therefore m\angle E = 2x\\
\& \: m\angle F = 5x \\
\because m\angle E + m\angle F = 70\degree \\
\therefore 2x + 5x = 70\degree \\
\therefore 7x = 70\degree \\
\therefore x = \frac{70\degree}{7}\\
\therefore x = 10\degree \\
\implies m\angle E = 2x= 2\times 10\degree = 20\degree \\
\& \: m\angle F = 5x=5\times 10\degree = 50\degree \\[/tex]
