(x+5)*7=133
7x+35=133
7x=98
x=98/7
x=14
Answer:
36
Step-by-step explanation:
Area of a triangle = (bh)/2
Where b = base length and h = height
Given base length: 18ft
Given height: 4ft
This being known let's define the variables
b = 18
h = 4
Now to find the area we simply plug in these values into the formula
Area = (18)(4)/2
Simplify multiplication 18 * 4 = 72
Area = 72/2
Simplify division
Area = 36
Answer:
Scalene
Step-by-step explanation:
Because all of the sides are different lengths
