Answer:
the area of the triangle is 41
the perimiter of the triangle is 33.25
Step-by-step explanation:
-7 * 3 = -21 so the answer is
-3 3/7
Answer:
7.7
Step-by-step explanation: We are trying to find side c or side AB
Using the law of sines formula,
a/sin a= b/sin b c/sin c we can solve for missing side.
We are given side BC or side a which is 11
We also are given angle A is 82 degrees
Angle C is 44 degrees also.
So let set up a proportion.
11/sin 82= x/sin 44
11/sin 82× sin 44=x
x= 7.7
Answer:
Area of rectangle is
Perimeter of Rectangle is
.
Step-by-step explanation:
Given:
Let the width of the rectangle be 'w'.
Also Given:
A rectangle has a length that is 5 meters greater than the width.
Length of rectangle = 
We need to write expression for Area of rectangle and Perimeter of rectangle.
Solution:
Now we know that;
Perimeter of rectangle is equal to twice the sum of the length and width.
framing in equation form we get;
Perimeter of rectangle = 
Also We know that;
Area of rectangle is length times width.
framing in equation form we get;
Area of rectangle= 
Hence Area of rectangle is
and Perimeter of Rectangle is
.
