First, you know that B is the mid point, meaning AB is equal to BC. Therefore, you can set up the equation: x+5=2x-11. Then, you solve for x. Once you are done solving, you should get 16. Hope this helps!
Answer:
50
Step-by-step explanation:
(2+3=5) +5 = 10
6+7 = 13
8+9=17
10
Then add them all together:
10+13+17+10=50
I think it’s seventy five
Answer:
-0.574
Step-by-step explanation:
Subtract the two numbers to get the solution
The angles in an equilateral triangle are 60 degrees.
sin 60 = 9 / h where h is hypotenuse ( = side of the triangle)
h = 9 / sin 60 = 10.392
Perimeter = 3 * h = 31.18 to nearest hundredth
