Answer:
The congruent angles are given below
Step-by-step explanation:
<u>Points to remember</u>
For parallel lines, Corresponding angles are equal
Vertically opposite angles are equal
<u>To find the congruent angles</u>
1). Angles congruent to <1 = <4, <8 and <5
2) Angles congruent to <2 = <3, <7 and <6
3) Angles congruent to <7 = <6, <2 and <3
4) Angles congruent to <6 = <7, <3 and <2
He worked for 12 days. 12 x 2 = 24
The first step is figuring out the length of the field. To do this, let's work backwards.
We are given the width (11m) and the perimeter (68m). We know that perimeter is measured with the formula P = 2W + 2L or W+W+L+L. All we have to do is plug in our width, 11(2) which is 22, and subtract that from the perimeter:
68 - 22 = 46 < this is the amount of both lengths combined, but in order to find the area, we only need one side. So, divide 46 by 2, and you'll get 23.
Now the area of a rectangle is found by using A = lw. So plug in your numbers and multiply 23 (length) and 11 (width). You should get 253.
Answer: 253m/D.
The sales was increased by 44.4%.
Step-by-step explanation:
- Lets do this cumulative
- 90 of 10 % = 9 which is 99
- 90 of 10 % = 9 which is 108
- 90 of 10% = 9 which is 117
- 90 of 10% = 9 which is 126
- 90 of 4 % = 3.6 which is 129.6
- 90 of 0.044% = 0.0396 which is 129.99
- This comes to nearly 44.44 to be closer there was an increase.
- Always rule 1 approximation use 50% of 90 if it is above 130.
- Down it to 40% of 90 see if the sales is lower than 130.
- It should always start with 50,40,30....10 percents.
- Alternative should be 10,1 or decimals.
- Approximation using decimals rounding up becomes simple.

= (t + 2v)(t + 2v)
= (t + 2v)^2</span>
