Instead, break down the shape into rectangles. Next, calculate the area of both rectangles and add them together. The area of the first rectangle is 72 square centimeters and the area of the second rectangle is 50 square centimeters. Together there are 72 + 50 = 122 square centimeters.
That is how u find a irregular figure..hope this help u
Answer:
you trying to figure out what is B?
B is isosceles triangles
Answer:
5 1/7
Step-by-step explanation:
5 1/7×7= 35+1=36 that's the answer
This is the application of trigonometry. The distance of the ladder from from the wall will be given by:
cos θ=(adjacent)/(hypotenuse)
θ=72°
adjacent=base (distance the ladder to base of the wall)= xft
hypotenuse=length of the ladder.
Therefore plugging our values in the formula we get:
cos 72=x/15
x=15 cos 72
x=4.635 ft
Hence we conclude that the foot of the ladder is 4.635 ft away from the base of the wall.
Answer:
Step-by-step explanation:
Given
From Figure
Sides of Triangle
Now, using concept
Perimeter of triangle = Sum of the sides of triangle
So,
Perimeter of triangle = 
Adding 
and 
, so,
Perimeter of triangle = 
This can be written as
Perimeter of triangle =
Adding 15 and 10,
Perimeter of triangle =
So, the correct choice is =
Hope this helps.
