The given triangle is an obtuse triangle. Option C is correct.

<h3>What is angle measurement?</h3>

An angle measure is the measurement of the angle created by two rays or arms at a shared vertex in geometry.

Angle less ess than 90-degree angles is considered acute. The right angle is 90 degrees. Angles that are obtuse are more than 90 degrees.

The acute, obtuse angles are 36⁰,132⁰ and none of the angles is the right angle.

The given triangle is an obtuse triangle.

Hence, option C is correct.

Add 3 feet 6 in add 3 feet 6 in + 8 ft 2 in + 4in + 2ft 5in what does that add up to

Troyanec [42]

Answer:

173 inches

Step-by-step explanation:

i don't entirely understand the question but i think you're trying to add 3 feet 6 inches + 8 feet 2 inches + 4 inches + 2 feet 5 inches?

(3 feet 6 inches) + (8 feet 2 inches) + (4 inches) + (2 feet 5 inches)

i've added these parentheses in order to make it easier to see the grouped measurements. this isn't necessary but i'm just doing it to hopefully aid my explanation since there's so many terms in the expression!

start by converting everything to inches just to make the addition as well as showing your work easier. all you have to do is multiply the amount of feet by 12 because there are 12 inches in a foot! :)

(3 feet 6 inches) + (8 feet 2 inches) + (4 inches) + (2 feet 5 inches)

for your first measurement, 3 feet 6 inches, convert 3 feet to inches by multiplying the amount of feet, 3, by 12.

3(12) = 36 (therefore 3 feet is equal to 36 inches!)

and add the remaining 6 inches.

36 + 6 = 42 (therefore 3 feet 6 inches is equal to 42 inches!)

(3 feet 6 inches) + (8 feet 2 inches) + (4 inches) + (2 feet 5 inches)

for your second measurement, 8 feet 2 inches, convert 8 feet to inches by multiplying the amount of feet, 8, by 12.

8(12) = 96 (therefore 8 feet is equal to 96 inches!)

and add the remaining 2 inches.

96 + 2 = 98 (therefore 8 feet 2 inches is equal to 98 inches!)

(3 feet 6 inches) + (8 feet 2 inches) + (4 inches) + (2 feet 5 inches)

nothing needs to be done to this quantity since it's already in inches.

(3 feet 6 inches) + (8 feet 2 inches) + (4 inches) + (2 feet 5 inches)

for your fourth measurement, 2 feet 5 inches, convert 2 feet to inches by multiplying the amount of feet, 2, by 12.

2(12) = 24 (therefore 2 feet is equal to 24 inches!)

and add the remaining 5 inches.

24 + 5 = 29 (therefore 2 feet 5 inches is equal to 29 inches!)

now, here is the expression with everything in inches.

42 inches + 98 inches + 4 inches + 29 inches aka 42 + 98 + 4 + 29

now add everything up!

42 + 98 + 4 + 29 = 173 inches

your total is 173 inches! i hope this helps and i hope i explained it well enough. have a lovely day! <3

What is the equation of the line shown in the graph? (-3,1) (2,-4)

ki77a [65]

Answer:

x + y = -2

Step-by-step explanation:

The two primary equations to remember when dealing with graphing 2-variable equations are: ax + by = c (a & b are the x & y coefficients, respectively), and the other is y = mx + c (m = slope, x & y represent themselves). There is another equation to find the slope. If not already known, it's: ∆y/∆x {∆(aka Delta) = difference}. So, since that's all been established, we can proceed to calculate your question:

1) Find your slope: 1 - (-4) = 5 for your y-variable. And -3 - 2 = -5 for your x-variable. So your slope = 5/-5 = -1

2) Use the y = mx + c equation together with either set of (x,y) coordinates to get the equation 1 = (-1)(-3) + c. Which gives you c = -2

3) So, going back to the main equation to remember, the ax + by = c, use a one of your given sets of x,y coordinates and input your known values for x, y, & c to get: a(-3) + b(1) = (-2) and do the same with other set (these are just double-checks, coefficients are all equal to 1 anyways). So, you should arrive to the equation: x + y = -2

14.What is the solution of the system?

Archy [21]

Answer:

14. x=-2.5, y = -7

15. x=28 y = -20

Step-by-step explanation:

14. Let's solve this system by elimination. Multiply the first equation by -1.

-1*(4x-y)= -1*(- 3)

-4x +y = 3

Then add this to the second equation.

-4x+y = 3

6x-y= - 8

--------------

2x = -5

Divide each side by 2

x = -2.5

We still need to find y

-4x+y =3

-4(-2.5) + y =3

10 +y =3

Subtract 10 from each side.

y = 3-10

y = -7

15.I will again use elimination to solve this system, because using substitution will give me fractions which are harder to work with. I will elimiate the y variable. Multiply the first equation by 11

11( 5x+6y)= 11*20

55x+66y = 220

Multiply the second equation by -6

-6(9x+11y)=32*(-6)

-54x-66y = -192

Add the modified equations together.

55x+66y = 220

-54x-66y = -192

---------------------------

x = 28

We still need to solve for y

5x+6y = 20

5*28 + 6y =20

140 + 6y = 20

Subtract 140 from each side

6y = -120

Divide by 6

y = -20
