Answer:
7 feet long
Step-by-step explanation:
This set up will give a right angle triangle where;
Length of the ladder is the hypotenuse = x
The distance of the ladder to the house is the adjacent = 3 feet
Angle of elevation theta = 72 degrees
Using the CAH in trigonometry identity;
cos theta = adjacent/hypotenuse
cos 72 = 3/hyp
hyp = 3/cos72
hyp = 3/0.4258
hyp = 7.05 feet
Hence the ladder is approximately 7 feet long

Answer:
1. The two numbers are 4 and 8.
Step-by-step explanation:
1) variables: x and y
2) x + y = 12, y - x = 4
3) graph using desmos or another graphing calculator
4) the solution is x = 4, y = 8, or 4 and 8. This means that 4 and 8 can be added to equal 12, and the difference between them is 4.
Answer: is x = -8
this is how i got it ______
6 x - 3 - 11 - 8 x = 2
(simplify both sides and combine like terms)
(6x + -8x ) + ( -3 + -11) = 2
- 2x + -14 = 2
-2x - 14 = 2
( then you add 14 to both sides)
- 2x - 14 = 2
+14 +14
-2x = 16
( then you divide both sides by -2)
-2x / -2 = 16/ -2
x = -8
ta da!! happy to help!
it made it here. this is for the second one.
( first, we subtract 8n from both sides)
13n + 26 = 8n - 29
-8n -8n
5n + 26 = -29
( then we subtract 26 from both sides)
5n + 26 = -29
- 26 -26
5n = - 55
(after that we divide both sides by 5, we do this to make n alone )
5n/ 5 = -55/ 5
n = -11
