Answer:
119
Step-by-step explanation:
By using exterior angle theorem, we know that 31+angle 1 =150. therefore angle 1=119. Exterior angle theorem is where an angle exterior of an angle in the triangle addus up to 180 degreees, we also know the angles in a triangle sum to 180 degrees. Both sides have a common angle. If we subract it from the equation, we get what is said above.
Ratios are simple if you know how. Simply put the two numbers next to each other with a : in between, then simplify.
Therefore, 5 flag stamps to 11 flower stamps has a ratio of 5:11. As both 5 and 11 are prime numbers, they cannot be simplified, so the answer is 5:11<span />
