Answer:
Step-by-step explanation:
For this triangle we have to
We want to find the length of b
We know that the sum of the internal angles of a triangle is 180 °
So
Now we use the sine theorem to find the length of b:
Then:
17 are older than 16 years old and 12 are taller than 170 cm
Minus 5 from both sides so we have 3a=-19 now divide both sides by 3 so we have a=-6 1/3
Yes because 2/6 divided in half is 1/3
