Answer:
The length is 15 yards
Step-by-step explanation:
Given
Represent the width with W and length with L: So


Required
Determine the length of the rectangle:
Area is calculated as thus:

Substitute 3W - 12 for L and 135 for Area


Reorder:

Divide through by 3

Expand:



or 
or 
But width can't be negative
So:

Recall that: 


<em>Hence, the length 15 yards</em>
Answer:
The correct answer is 6 cm.
Step-by-step explanation:
The measure of all angles of the triangle is given to be 60 degrees. This invariably means we are talking about an equilateral triangle as all angles of an equilateral triangle are equal.
Also all sides of an equilateral triangle is known to be equal. Therefore the measure of all sides of the concerned triangle are equal.
Given the measure of two length of sides are 6 cm respectively.
Therefore the length of side 3 is 6 cm, equal to the other two sides.
The answer to ur question is 20.94395.
If one third of t is 7 than t is equal to 21
Answer:
x° =125° y°= 125°
Step-by-step explanation:
55° + x° = 180° because they are complementry angles
solve for x by subtracting 55° from both sides
x° = 125°
x° and y° is equal because they are vertical angles
