Answer
the one on the opposite side of the 137 is 137. the other part of that is 43 and 43. on the bottom one it is 117 on the obtuse angles and 53 on the acute angles. I hope this helps and doesn't sound crazy. I cannot remember the terms. I learned it a couple months ago.
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
We can write the equation as 16 + x = 19
To solve we can work backwards, I know the opposite of adding is subracting... so 19 - 16 = 3 which means x is equal to 3.
Hope that helps and have a great day!
Solution:
<u>We know that:</u>
- Perimeter of rectangle = 2L + 2B
<u>Given:</u>
<em>Substitute the values into the expression to find the perimeter.</em>
- Perimeter of rectangle = 2L + 2B
- => 2(9) + 2(5)
- => 18 + 10
- => 28 cm
We are given the total earnings of the school, $2800.
The earnings of each grade level are as follows:
2nd grade = $200
5th grade = $200
kindergarten = 2 * $200 = $400
4th grade = 2 * $200 = $400
1st grade = 3rd grade = x
The amount which is left for us to determine is the earnings of the first and third grade. This can be determined by equating all earnings to the total school earnings and let 1st and 3rd grade be the variable x:
$2800 = $200 + $200 + $400 + $400 + x + x
$2800 = $1200 + 2x
$1600 = 2x
x = $800
Therefore, 1st grade and 3rd grade earned $800 each. <span />
