Answer:
Step-by-step explanation:
<u>Perimeter formula is:</u>
<u>Given:</u>
- l = 2x - 2 and w = x
- P = 86 m
<u>Substitute and solve for x:</u>
- 2(2x - 2 + x) = 86
- 3x - 2 = 43
- 3x = 45
- x = 15
<u>Then find the values of l and w:</u>
- l = 2*15 - 2 = 28 m
- w = 15 m
Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient.
Step 2: Subtract the second equation from the first.
Step 3: Solve this new equation for y.
Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.
Answer:
D. 
F.
Step-by-step explanation:
We have been given an image of a triangle and we are asked to choose the remote interior angles of angle 1.
Since we know that remote interior angles are the two angles that are inside the triangle and opposite from the exterior angle.
We can see that angle 1 is exterior angle of our triangle and and angle 4 an 6 are opposite interior angles of angle 1.
Therefore, angle 4 and angle 6 will be remote interior angles of angle 1 and options D and F are correct choices.
