13-6=7 is a other way to write it.
Yes. Supplementary angle is one which when added to the angle makes 180 degrees. Thus, if the angle is acute, its supplementary angle would be obtuse.
Answer:
Graph One.
Step-by-step explanation:
See below. The graph is in a straight line, also known as linear. The other graphs are not. Also, if you look at the range (y) of the tables, you can see the increase is linear as it is increasing by .5 (1/2) everytime.
Answer:
Step-by-step explanation:
im gonna go out on a limb and say (B)
We are given a right triangle whose legs we name as x, x+2 and x+4. The Pythagorean theorem states that the square of the hypotenuse's length is equal to sum of the squares of its legs. hence, we apply this to the given data:
a2 + b2 = c2
We substitute the given data
x2 + (x+2)2 = (x+4)2
We expound the given squares
x2 + x2+ 4x + 4 = x2 + 8x +16
We group next the like terms
2x2-x2 = 8x -4x + 16 -4
x2 = 4x + 12
(x2-4x-12) = 0
we factor the given quadratic equation
(x-6)*(x+2) = 0
x1 = 6
x2 = -2
The valid solution set would be 6 since there are no negative measurements, so the answer to this problem would be 6+2 = 8 units.
