Step-by-step explanation:
<1 = 90 - 32
= 58
bd is a traversal to parallel line ab and dc
<1 = <bdc ( alternate angles) = 58
in right triangle edc
90 - 58 = <3 = 32
<2 = 58
<span>Total surface area of Prism = Lateral surface area + area of top and bottom
.......................................= Perimeter of base * height + 2* area of base (as top and bottom same)
Tot. surface area of Prism = P*h + 2B ( where B is area of base, and P is perimeter h is height)
so what is hP -----------> lateral surface area</span>
Answer:
Question 6: -8
Question 7: C
Step-by-step explanation:
Question 6:
The reason question 6 is -8 is because of the distance in between each number, e.g -7 and -15. This is not to be confused with + 8 each time that would make the sequence 9, 18, 27.
Question 7:
The way we solve this question is using the nth term rule, whatever is before the n is the times tables we follow. So if it is 2n the sequence would be 2, 4, 6, 8 etc. However when we add something like the -2 we do the 2 times tables but this time we -2 for each one. Example: 2 - 2 = 0 so the first number of the sequence is 0, Example 2: 4-2 = 2 so the second number of the sequence is 2.
Answer:
