Answer:
C
Step-by-step explanation:
∠ AFD = ∠ AFC + ∠ CFD
Given ∠ CFA = 90° and
∠ CFD = 90° - ∠ EFD, that is
∠ CFD = 90° - 62° = 28°, thus
∠ AFD = 90° + 28° = 118° → C
When
the perimeters of both figures will be equal.
Step-by-step explanation:
Step 1:
The triangle has side lengths of
and
.
The perimeter of the triangle is the sum of the lengths of the sides.
The perimeter of the triangle 
Step 2:
The perimeter of the hexagon is 6 times its side length. The side length 
The perimeter of the hexagon
Step 3:
To determine the value at which both the perimeters are equal, we equate both the equations to each other.

So when
the perimeters of both figures will be equal.
Answer:
4
Step-by-step explanation:
from 13 to 15 you added two more so you have to do 8 divided by 2 which is 4
The value of z is zero
Step-by-step explanation:
The slope is the steepness of the line.
The formula for slope is given by:

Here
(x1,y1) = (1,z)
(x2,y2) = (2,8)
So,

The value of z is zero
