If you would like to solve the equation 2 * (x + 4) = 30, you can calculate this using the following steps:
2 * (x + 4) = 30
2 * x + 2 * 4 = 30
2 * x + 8 = 30
2 * x = 30 - 8
2 * x = 22 /2
x = 11
The correct result would be B. 11.
Answer:
19 sin + 20 cosec
explanation
9 sin A + 10 sinA + 33 -13 cosecA
19 sin + 20 cosec
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
