Answer:
30
Step-by-step explanation:
We can ignore the fact they are similar altogether. It's known that all 3 angles of a triangle add up to 180, so:
180=102+48+m
180=150+m
30=m
I think the answer is positive.
Hope this helps!
Since it is the perimeter you add all the sides, so it is 5 1/2 + 5 1/2 * 6= 15, so the perimeter is 15:)
12/13
sin = opposite / hypotenuse
