Pete will need 10 ounces of turkey.
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
X = smallest angle, y = middle angle, z = largest angle
x + y + z = 180...interior angles of a triangle add up to 180 degrees
y = 1/2z.....z = 2y
y = 3x.......1/3y = x
1/3y + y + 2y = 180....multiply everything by 3
y + 3y + 6y = 540
10y = 540
y = 540/10
y = 54 <== the middle angle
z = 2y
z = 2(54)
z = 108 <=== largest angle
1/3y = x
1/3(54) = x
54/3 = x
18 = x <=== smallest angle
Answer:
a= c/7b
Step-by-step explanation:
Divide each term by 7b and then simplify.
Hope this helps.
