Question

I dont understand help

Answer 1

x=16 y=5

Explanation:

Since triangle ABC is an equilateral all sides are equal. Since they are all equal you can do 49=3x+1 You then subtract one to the other side to get 48=3x then you divide 3 by 48 which is 16=x. For y you would do the same thing. 49=18y-41. Now you add 41 to 49 and get 90=18y. You divide 18 by 90 and get 5=y. If you want you can always check your answer by doing Taking the original problem and placing the x or y value where the variable is and is should equal to 49

Answer 2

Because the triangle equilateral ( all sides are equal) This means that all sides will be equal to 49
49=3x+1
49-1=3x
48=3x
X=16

49=18y-41
49+41=18y
90=18y
Y=5

Hope this helped
