So the equation for a trapezoid is

, with the b variable being the 2 bases, h variable for height, and the a variable for area. Firstly, we will need to plug in the appropriate numbers into the equation, and it'll look like this:

Next, we will need to combine 12 and 14, then divide the sum by 2. Your equation should look like this:

Lastly, just divide each side by 13, and your answer should be
Answer:
= -43
Step-by-step explanation:
Evaluating the expression;
(–1)8 + (–1)7 + –16 + –14 – (–1)2
We can use Bodmas
We remove the brackets first
(–1)8 + (–1)7 + –16 + –14 – (–1)2
We get
-8 + - 7 + -16 + -14 - -2
but; - × + = - and - × - = +
Thus;
-8 - 7 - 16 - 14 + 2
= -8 -7 - 16 - 12
<u>= -43 </u>
Answer:
50.007131355
Step-by-step explanation:
A calculator lol?
0.5 or 6 inches
The model=32
Actual size=1
32/1= 16/?
If 32 is 1 foot which equals 12 inches, and 16 is half of 32, then 16 is 0.5 inches or 6 inches
Let the ladder length be L, then
sin 70 = 20/L, L = 20/sin70 = 21.3 feet
the length of ladder is 21.3 feet
