Brian wants to build a ramp that leads to a storeroom 5 meters above the ground. he wants the ramp to be 10 meters long. what should the angle of elevation of the ramp be?

The angle of elevation is 26.5650(3dp)

Let h be the end height of the ramp above the ground , l be the length of the ramp and the angle of elevation is θ∴tanθ=hl=510=0.5∴θ=tan−1(0.5)=26.5650(3dp)[Ans]

30 is the answer

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
