Answer:
zero because the when adding two of the side lengths they do not equal the third side length. Side lengths do not adhere to the triangle inequality theorem. which states that the sum of the side lengths of any 2 sides of a triangle must exceed the length of the third side. I think thats right.
Step-by-step explanation:
7+2 = 9 not 10
By definition <span>a2=b2+c2</span>, so if b<0 or c<0 or both, b2 and c2 will (always) be positive, and so their sum will always be positive, therefore the hypotenuse, a<span>, will always be positive.

Answer is A. 18
Because n + 18 =2n
Plug in 2 for x. f(20=2-51 = -49
Answer:
R=22
Step-by-step explanation:
180-44= 136
136÷2= 68
90-68= 22
180 is angle of the straight line. 44 is subtracted to get angle of only the triangle on the left which is 136. 136 is then divided by 2 since the remaining two angles are equal and you'll get 68. R is part of a right-angled triangle (90°) subtract 68 from that and you will get 22
