The length of the support post is 40 ft.
<u>Solution:</u>
Given, the height of the wall is 20 ft; support post forms 30 degree
Refer the attached image
Let us name the triangle as ABC where AB is the wall (opposite side) of 20 ft and is 30 degree () and AC is the length of the post.
To find: The length of the post (AC)
we know the formula, (trigonometric formula)
On substituting the values we get,
The value of sin 30 degree is 0.5
Answer:
1)4x+4y=1, 6x−y=1
x+y=4, x−y=2
x+y=−2,x+2y=2
2)2x+y=3, 2x−8y=19
Step-by-step explanation:
hope this helps
have a nice day ^_^
Let x equal the larger number
Let y equal the smaller number
x+y=63
x=y+11
Sub the second equation into the first equation and solve for y
y+11+y=63
2y+11=63
2y=63-11
2y=52
y=52/2
y=26
Sub y into the second equation
x=y+11
x=26+11
x=37
Hope this helps!
