Answer:
51.9
Step-by-step explanation:
because one side is 30 and another is 60, you can assume the 3rd side of the triangle is 51.9 because of the 30-60-90 rule which states that if each angle of a triangle is 30, 60, and 90, then the side lengths equal x (30), 2x (60), and x√(3) (~51.9).
X - 3y=0
3y - 6 =2x
__________
x - 3y=0 ........(1)
-2x + 3y=6 ........(2)
__________
-x = 6 ==》x = -6 .........(3) subst. in (2)
-2 (-6) + 3y = 6 ==》3y= -6 ==》y = -2

Answer:
9, 13, 22, 38, <u>63</u>, <u>99</u>
Step-by-step explanation:
13 = 9 + 2²
22 = 13 + 3²
38 = 22 + 4²
