Answer:

57°

Step-by-step explanation:

The ladder will be the hypotenuse while the 4.2 meters will be a leg.

We want the angle between the ground & the ladder. Therefore, 4.2 is on the opposite side of the angle.

sin(theta) = opposite/hypotenuse

sin(theta) = 4.2/5

theta = arcsin(4.2/5)

theta = 57°

What’s the term 15 points !!!
Zielflug [23.3K]

Answer:

Domain

Step-by-step explanation:

The <u>domain</u> tells you all of the possible x-values in a set of data.

The example uses ordered pairs written as (x, y), and takes out all of the x-values. It wrote the domain in set notation (which is when the { } curly-styled parentheses are used).

Do not confuse domain with range. Range means all of the y-values in a relation.

In the provided example, the range would be {3, 4, 5, 7}.

How do I do this. Due tomorrow
kolbaska11 [484]
I prefer D.

It's clear that Kevin took (1/4)x.
Keith took (1/4)x -> kevin's amount
                 * 2      -> twice.
                 -1       -> 1 less.

So Kevin + Keith = (1/4)x + (1/4)x * 2 - 1 = (3/4)x - 1.

Answer:

10m

Step-by-step explanation:

We can set up an equation to solve this.

\frac{20}{25} =\frac{8}{x}

This equation can be created since we are given two similar sides of both triangles.

Now, cross multiply and simplify to solve for x.

20x=200\\x=10

The answer is sensible, and if you put 10 into the same equation from earlier, you will see that it is accurate.

Therefore, the value of x is 10m.
