The perimeter of the triangle is 120
explanation:
the formula of a perimeter is LxW ( length times width )
15x8= 120
Answer:
I believe it is A
Step-by-step explanation:
The <em><u>correct answer</u></em> is:
x=6/7.
Explanation:
First we find the general form by solving for x:
a-bx = cx+d
Subtract a from each side:
a-bx-a = cx+d-a
-bx = cx+d-a
Subtract cx from each side:
-bx-cx = cx+d-a
-bx-cx = d-a
We can divide both sides by -1:
(-bx-cx)/-1 = (d-a)/-1
bx+cx = -d+a
bx+cx = a-d
Factor out an x on the left:
x(b+c) = a-d
Divide both sides by (b+c):
(x(b+c))/(b+c) = (a-d)/(b+c)
x = (a-d)/(b+c)
In this equation, a = 5, b = 6, c = 8 and d = 17:
x = (5-17)/(6+8) = -12/14
This simplifies to -6/7.
The ex- suffix often correlates a word to mean "outside", while the in- suffix often correlates a word to mean "inside". An exterior angle of a polygon would mean "an angle outside of a polygon". An interior angle of a polygon would mean "an angle inside of a polygon". Three exterior angles of this polygon would be angle B, angle D, and angle A. This is because these angles are outside of the polygon due to the extending lines from the shape. Two interior angles of this polygon would be angle 6 and angle 8 (explanation was given when I first began answering this question). Angle 9 would be exterior since it is outside of the polygon. Two exterior angles of the polygon that are congruent are angle D and angle 9, since they are both 90 degrees (right angles).
