Answer:
Perimeter: 15 feet, Area: 15 square feet.
Step-by-step explanation:
You need this fast, so I'll spare you of much description. Add the side lengths for perimeter, and multiply the sides that aren't the hypotenuse (the legs) for the area.
Answer: x =104
Step-by-step explanation:
If we draw the black line shown in the figure, two isosceles triangles are formed, and the base angles of the isosceles triangles are the same. The red angles are the same and the green ones too. The 104 degree angle is the sum of the red angle and the green angle, and x is also the sum of the red angle and the green angle, therefore x = 104.
Answer:
15 metres
Step-by-step explanation:
perimeter of rectangle = 2(base + height)
=2(8+h) = 46
= 16 + 2h = 46
= 2h = 46 - 16
= 2h = 30
= h = 15
15 metres is the height of rectangle
Answer:
10
Step-by-step explanation:
First, multiply everything in the parentheses.
Next, subtract 21x from both sides to get all the variables on one side.
Next, add 16 to both sides to get all the real numbers on one side
Finally, divide both sides by 30 so we can get the variable by it's self
