Need help in solving this area of the shape attached
dybincka [34]

Answer:

105 cm squared

First find the area of the rectangle

length x width = area

6 x 15 =90

Now find area of triangle

subtract 11-6 and 15-9 to get the dimensions for the triangle

5 and 6 are the dimensions

Length x height / 2 = area of triangle

5 x 6 = 30

30 / 2 = 15

add the areas together

90 + 15 = 105

105 cm squared

hope this helps

Write the measure 29° 6' 6" as decimal to the nearest thousandth.
den301095 [7]
This angle is "29 degrees 6 minutes 6 seconds".

-- There are 60 minutes in 1 degree. 
     So 1 minute = 1/60 degree.

-- There are 60 seconds in 1 minute. 
      So 1 second = 1/60 minute = 1/3600 degree.

  29  6'  6"  =  (29)° + (6/60)° + (6/3600)°

                   =  (29)° + (0.1)° + (0.001666...)°

                   =        29.101666...°

Rounded to the nearest thousandth of a degree:  29.102°

108 - 271 + 215-_____= -103
kupik [55]
108-271+215-_____=-103
Im going to combine the first thee numbers and replace the blank with a variable, lets use x. 
52 - x=-103
now I am going to subtract 52 on both sides to get the variable alone
-x=-155
Im going to multiply both sides to eliminate the negitive in the variable
x=155
If you want to check just plug 155 into the blank
108-271+215-155=-103
-163+215-155=-103
52-155=-103
-103=-103

so after checking work the blank is equal to 155.
