Answer:

Trigonometry can be used to measure the height of a building or mountains

Step-by-step explanation:

if you know the distance from where you observe the building and the angle of elevation you can easily find the height of the building. Similarly, if you have the value of one side and the angle of depression from the top of the building you can find and another side in the triangle, all you need to know is one side and angle of the triangle.

Solve -1 3/8 K equals 2/3

guajiro [1.7K]

Answer:

K = -16/33

Step-by-step explanation:

For a problem like this, it is convenient to write the mixed number as an improper fraction:

Now, multiply the equation by the reciprocal of the coefficient of K.

K = (-8/11)(2/3)

K = -16/33

Add the two expressions.<br><br> −2.4n−3 and −7.8n+2

Sphinxa [80]

Answer:

-10.2n - 1

Step-by-step explanation:

We have two expressions in variable n and we have to add the two expressions.

An important thing to note is that only like terms can be added. i.e. the term with "n" can only be added or subtracted to the term with "n". Similarly a constant can only be added or subtracted to a constant.

$(-2.4n-3)+(-7.8n+2)\\=-2.4n-3-7.8n+2\\=-2.4n-7.8n-3+2\\=-10.2n-1$

Thus, the two given expressions add up to -10.2n - 1

The ratio of the width to the length of a flower is 10:19. How long is the flower bed if it’s width is 6 feet?

Lubov Fominskaja [6]

Just set up an equation comparing the two ratios and solve for the length, in this case x.

(10/19)=(6/x)
19/10=x/6
114/10=x

Answer= 11.4 feet for the length of the flower
