For the first question on the screenshot, you need to put this same exact order as I put it.
A D B C
Now the second question
A = 3 units
B = 4 units
C = 4 units
D = 3 units
Answer:
20. 44
21. 9
22. 94
23. 116
24. 17
25. 13
Step-by-step explanation:
Keep in mind complementary and supplementary angles. When two angles are right next to each other on a straight line, they add up to 180 degrees, such as the angles in 22 and 23. The other two angles are complementary angles since they add up to 90 degrees. So to solve for b, subtract the angle you are given from either 90 or 180 depending on if it is complementary or supplementary.
For question 20:
90 = b + 46
90 - 46 = b
b = 44
Then do the same for 21.
For question 22:
180 = b + 86
180 - 86 = b
b = 94
Then do the same for 23.
For the last two questions you need to remember that angles that are diagonal from each other are equivalent angles, so they equal each other.
For question 24:
70 = 4x+2
68 = 4x
x = 17
Do the same for 25.
83 = 6x+5
78 = 6x
x =13
Answer:
what is the question
Step-by-step explanation:
Answer:
n² - 6n - 16
Step-by-step explanation:
As per the question,
We have been provided the equation
(n-8)(n+2)
To find the product, we have to multiply the both term,
(n - 8) (n + 2)
= n (n + 2) - 8 (n + 2)
= (n² + 2n) - (8n + 16)
= n² + 2n - 8n - 16n
= n² - 6n - 16
Hence, the required answer of the product of (n-8)(n+2) = n² - 6n - 16.
Answer:
7.2
Step-by-step explanation:
Since 72 goes into 10 7 times, we do have 7 point something. We are left with 2/10ths, which is 0.2, so we add them together to get 7.2.
