Question

Angles E and Fare in ration 2:5. If the sum of E+F=70, What are the

Answer 1

Answer:

$m\angle E = 20\degree \\m\angle F = 50\degree$

Step-by-step explanation:

Let the common multiplier of the given ratios be x.

$\therefore m\angle E = 2x\\\& \: m\angle F = 5x \\\because m\angle E + m\angle F = 70\degree \\\therefore 2x + 5x = 70\degree \\\therefore 7x = 70\degree \\\therefore x = \frac{70\degree}{7}\\\therefore x = 10\degree \\\implies m\angle E = 2x= 2\times 10\degree = 20\degree \\\& \: m\angle F = 5x=5\times 10\degree = 50\degree$

Answer 2

Answer:

E is equal to 20 and F is equal to 50. 20(E)+50(F)=70
