Answer:
m<6 = 130°
Step-by-step explanation:
If m∠2 = 130°, what is m∠6?
Find the diagram attached
From the digram we can see that the vertical lines are parallel. Hence based on geometry;
m<2 = m<6 (corresponding angles)
Given m<2 = 130°, hence m<6 = 130°
Answer:
Option C. 4(20-16y): Each side measures 20-16y units.
Step-by-step explanation:
we know that
The perimeter of a square is equal to
where
b is the length side of the square
we have
substitute the given value in the formula
solve for b
Divide by 4 both sides
Rewrite the expression
<em>Alternative Method</em>
we have
Factor 4
so
Each side measures (20-16y) units.
Answer:
Step-by-step explanation:
We know that the length is four times the width, so:
We also know the area, which is 324 m². The formula for area:
Insert the known values:
Solve for w. Simplify by removing parentheses:
Divide 4 from both sides to isolate the variable:
Find the square root of both sides:
The width is 9 m.
We know the width. Now find the length by using the area formula and inserting known values:
Solve for l. Divide both sides by 9:
The length of the rectangle is 36. (You can check: 4 times 9 is 36)
Now find the perimeter:
Insert values:
The perimeter is 90 m.
