The area of trapezoids is a=1/2h(b1+b2)
So: a=1/2 19 45(25+22 1/2)

The answer is 940 1/2 by first you will have to add the length soo...
22 1/2 +25 is 47 1/2
But then you will have to 47 1/2 and 19 4/5 into a mixed number..
47 1/2 = 95/2
19 4/5 = 99/5
Then you multiply 95/2 and 99/5 and get 9405/10.After that then you will divide 9405 by 10 and you should get 940.5 which is also equal to 940 1/2 ft

Hopes this helps! ( ͡° ͜ʖ ͡°)

Answer:

Number 3 is correct.

129.19m

Step-by-step explanation:

You might be wondering how did I got 32⁰, well, that's because they are alternate angles.

Now, we're trying to find the opposite side of the triangle.

Using the laws,

we got cos32⁰=x/243.8

243.8cos32⁰=x

129.19⁰

Explain how you know 7/12 is greater than 1/3 but less than 2/3

Roman55 [17]

7/12
1/3=4/12
2/3=8/12

7/12>1/3
7/12<2/3

convert all of these to a common denominator:
7/12 , 1/3 , 2/3
---
7/12 = 7/12
1/3 = 4/12
2/3 = 8/12
---
place into compound inequality:
---
(1/3=4/12) < (7/12=7/12) < (2/3=8/12)
