Mathematics

maksim [4K]3 years ago
8 0

Answer:

\boxed{AC = 42.99}

Step-by-step explanation:

Tan 34 = \frac{opposite}{adjacent}

Where opposite = 29, adjacent = AC

So,

0.674 = \frac{29}{AC}

AC = \frac{29}{0.674}

AC = 42.99

Someone please help me, and it says find the value of x and y.
mars1129 [50]
To find x:
Triangles are in total 180 degrees. The two triangles are basically 1 triangle split in half. If the triangle share the same side, has similar angles (shown by the curves on both sides at the top(Angle BAC and CAB), and has similar sides(shown by the hashes made in the lines AC & AB), you can conclude 'x' as a 90 degree angle.
To find y:
The measurment of the angle DCA is 47 degrees. For x, we concluded the answer to be 90 degrees, making the other side of the line 90 degrees as well.Since a triangle is 180 degrees, we can add 47 and 90 to get 137. Taking that answer, we subtract it from the value of 180 degrees to get 43 degrees. So y equals 43.

What is a negative minus a negative
Rainbow [258]

Answer:

It would be a negative or positive depending on the situation.

Step-by-step explanation:

A negative minus a negative would result in either a positive or negative. For example, -8 - (-9) would be 1 while -8 - (-7) would be -1. If the negative number your subtracting is greater than the number you're subtracting from then it will be positive, vice versa.

Look at the Schoology problem provided below.
lys-0071 [83]

Answer:

k = 4 units

Step-by-step explanation:

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

k² + 7.5² = 8.5²

k² + 56.25 = 72.25 ( subtract 56.25 from both sides )

k² = 16 ( take the square root of both sides )

k = \sqrt{16} = 4

An apartment rents for $800 a month the monthly rent is expected to increase $15 each year what will the rent at the end of the
Nataly [62]
To find this you would do 800 + 15x where x is the amount of years. 

For 9 years it would be 800 + 15(9) which is 800 + 135. 

At the end of 9 years, the apartment's rent would be $935. I hope that's utilities included because... yikes...
