Answer:

x = 33.8°

Step-by-step explanation:

The resulting diagram we have is a right triangle. To find x, apply trigonometric function.

Reference angle = x

Opposite = 116

Adjacent = 173

Apply TOA:

Tan x = Opp/Adj

tan (x) = \frac{116}{173}

x = tan^{-1}(\frac{116}{173})

x = tan^{-1}(\frac{116}{173})

x = 33.8° (nearest tenth)

Someone please help i beg you :((((
ladessa [460]

Answer:

From Newton’s second Law

F = ma

a = Fm = 300 N /(30 kg + 10kg) =

300 N/(40 kg) = 7.5 m/s2

Note: Sled mass is added because person will accelerate along with it.

It seems that the questions is to be a physics subject

Thank you and please rate me as brainliest as it will help me to level up.

The number of cows in a farm was 60% of the number of the goats. After 80 goats were taken out of the farm, the number of goats
Eva8 [605]
Before:
The number of goats =60%
The number of cows = 100%

Using ratio
Cows : Goats
60 : 100 reduced to simplest term

C:G
3:5

After
The number of cows = 100%
The number of goats = 60%

Using ratio

C:G
100:60 reduced to simplest term
C:G
5:3

Number of cows remained constant. Therefore find the common multiple.

Before
C:G
15:25

After
C:G
15:9

Find the difference in the units of goats

(a)25 - 19= 16
16 units =80
1 unit = 5
15 units (cows) = 5 x 15 = 75
There were 75 cows.

(B)
Number of goats at first
25 units = 5 x 25 = 125
Therefore percentage= 80/125 x 100
= 64%

Find anequation for the perpendicular bisector of the line segment whose endpoints are(3, -1) and (-9,5).
Mariulka [41]

The perpendicular bisector goes through the midpoint.

What is the midpoint of the 2 points?

We simply add up the x points and divide by 2. Then we add up the y points and divide by 2.

So,

Midpoint is:

(\frac{3-9}{2},\frac{-1+5}{2})=(-3,2)

Also, the perpendicular bisector's slope is the negative reciprocal of the line's slope.

The slope of the line is change in y points divided by change in x points.

Slope =

\frac{5--1}{-9-3}=\frac{5+1}{-12}=\frac{6}{-12}=-\frac{1}{2}

The slope (m) of the perpendicular line (negative reciprocal) is basically:

2

Equation of line is:

y-y_1=m(x-x_1)

m is the slope (what we got "2")

x1 and y1 are the respective point where it passes through (which is the midpoint, which is (-3,2)

So, equation of perpendicular bisector is:

\begin{gathered} y-y_1=m(x-x_1) \\ y-2=2(x+3) \\ y=2x+6+2 \\ y=2x+8 \end{gathered}
