4x-30=180 your missing the 180 part because it’s a straight line. so do 4x-30=180. subtract 30 from 180, then when you get that answer divide it by four
I think the error is that you did not divide 6 by 2 first because you are supposed to so you would get 3, then you do 1 times 3 which is 3, then you have 3 plus 3 left which would be 6. i’m hoping this is right and that it helps you
**CORRECTION** 21/2 because when you simplify it (dividing the top and the bottom by 2) you get 21/2. My first asnwer was a mixed number
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees.
In radians this are
To find the complement of 3π/4, subtract it by π/2
To find the supplement of 3π/4, subtract it by π.
Answer:
C. 336 cm²
Step-by-step explanation:
Area formulas:
Area of a right triangle: a × b ÷ 2
Area of rectangle: length × width
-----------------------------------------------------------------------------------------------------------------
In this figure, there is a rectangle with a width of 12 and a height of 6.
; the area of the rectangle is 72 cm².
There are two right triangles with legs of 6 and 8.
There are two right triangles so..
The area of a single triangle is 24 cm²; the area of the triangles combined is 48 cm.
There is a rectangle in the middle with a width of 8 and a height of 12.
The area of the rectangle is 96 cm².
Lastly, there is a rectangle with a width of 10 and a height of 12.
The area of the rectangle is 120 cm².
Now, add the areas of every shape to find your answer.
Step-by-step explanation:
