Answer:
.
Step-by-step explanation:
D. 17 inches
To be a triangle, any two sides have to add to be larger than the remaining side. An isosceles triangle has two sides that are the exact same length, which eliminates options B and C. 8 + 8 = 16, which is less than 17, so option A is out, leaving only option D.
Because you have an percentage, you have to move two decimal places to the front, you'll get .34 and multiply it by 66. Finally, your final answer is 22.44
Okay so x+5 =22 is x=17. 2x + 8 = 12 is x = 2
