Answer:
27 inches
Step-by-step explanation:
Combined perimeter = perimeter of rectangle + perimeter of triangle = 63 inches
Perimeter of rectangle = 2(L + W)
L = 11 in.
W = 7 in.
Perimeter of rectangle = 2(11 + 7) = 36 in.
Let perimeter of the triangle be represented by x
Therefore:
36 + x = 63
Subtract 36 from each side
x = 63 - 36
x = 27
Perimeter of triangle = 27 inches
Answer:

Step-by-step explanation:
To find the slope, rearrange the equation to y=mx+b or y=mx+c.

Subtract 4x from both sides:

Divide 5 on both sides:


In the equation of y=mx+b/y=mx+c, m will be the slope.
Therefore, the slope is 
A right angle is an angle at 90 degrees
