The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is nine times the measure of the first angle. The third angle is 26 more than the second. Let x, y, and z represent the measures of the first, second, and third angles, respectively. Find the measures of the three angles.

Answer:

98

Step-by-step explanation:

Hello There!

The angle that has a measure of 82 degrees and the angle labeled "2" are supplementary angles.

This meaning that the sum of the two angles is 180

So to find the missing angle (2) we subtract the given angle (82 in this case) from 180

so ∠2 = 180 - 82

180 - 82 = 98

Hence, the answer is 98°

Answer:

384 cm²

Step-by-step explanation:

Since it is a square pyramid, the total surface area of the pyramid is the area of its square base plus the area of its 4 triangular faces.

[tex]\boxed{area \: of \: triangle = \frac{1}{2} \times base \times height }[/tex]

Area of a triangular face

= ½ ×12 ×10

= 60 cm²

[tex]\boxed{area \: of \: square = side \times side}[/tex]

Base area of pyramid

= 12 ×12

= 144 cm²

∴ Surface area of pyramid

= 4(60) +144

= 240 +144

= 384 cm²

Answer:

$340

Step-by-step explanation:

Given data

Inititial fee= $100

cost per minute= $1

Let the total charge for x minutes by y

Hence the expression for the total charges after x minutes is

y= 100+1x

y=100+x

But an after is from 12pm - 4pm= 4 hours

x=4*60

x=240minutes

y=100+240

Answer:

68% increase and 91% increase

Step-by-step explanation:

220(1+x)=370 --  220(1+rate increase)=370

1+x=1.68

x=.68

220(1+x)=420  (370+50)=420

1+x=1.909

x=.91

Answer:

8 plantains

Step-by-step explanation:

48=$24

x=. $4

192=24x , x= 192÷24= 8

Answer:

8 plantains

Step-by-step explanation:

Cost and number of plantains are in proportion

Number of plantains that can be bought for $ 4 be 'x'

48 : 24 :: x : 4

Product of means = product of extremes

24 * x = 48*4

       [tex]x = \frac{48*4}{24}[/tex]

      x = 2 * 4

      x = 8

Answer:

Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

Answer:

Step-by-step explanation:

The number of filled bags will be 35 for each hour (x) that Jackson works, in addition to those already filled. So, the total number filled after x hours is ...

  35x + 20

We want that number to be at least (greater than or equal to) 1000, so the relation is ...

  35x +20 ≥ 1000

__

To solve this, we first subtract 20:

  35x ≥ 980

Now, we can divide by the coefficient of x.

  x ≥ 980/35

  x ≥ 28 . . . . .  the solution

Triangle Area:

TA = 3×4/2 = 6 in²

Probability:

P(point not in circle) = (6-π)/6 ≈ 0.48 ≈ 47.64%

the answer is (-8) because x=4, y=-6, z=11

These consists of more than 1 equation with unknown variables. The value that is not a solution in (x,y, z)is -8

These consists of more than 1 equation with unknown variables. Given the set of equations

x+y+z=9

x-y-z=-1

x-y+z= 21

Add 1 and 2

2x = 9 - 1

2x = 8

x = 4

Subtract 2 and 3

-2z = -22

z = 11

Determine the value of y

x +y + x = 9

4 + y + 11 = 9

y = 9 - 15

y = -6

Hence the value that is not a solution in (x,y, z)is -8

Answer:

  5/2 = 2.5

Step-by-step explanation:

The slope is given by ...

  m = (y2 -y1)/(x2 -x1)

Using the first two lines in the table, this is ...

  m = (10 -5)/(2 -0) = 5/2

The slope of the line is 5/2.

Answer:

Step-by-step explanation:

It would be 2.43ft cubed. You first have to multiply 6 x 9 to get 54 and then Do 54 x 4.5 to get 243 ft cubed. Next you have to put it in fraction form 243/100. After that you have to divide 243 by hundred( you can do this by moving the decimal place two places to the left) and you get the answer 2.43 ft cubed

Answer:

x =30/19 and y =2/19

Step-by-step explanation:

5x + y = 8

x + 4y = 2

then

5x + y = 8

-5(x +4y =2)

5x + y = 8

-5x - 20y = - 10

0 +y - 20y = -2

- 19y = -2

y = 2/19 then

5x + 2/19 = 8

5x = 152-2/19

5x/5 =150/19 *1/5

x =30/19

Answer:

Chapter Three: Calculate Total Countertop Square Footage

To calculate the total square footage (after placing seams) you will need to follow this formula: “L” x “W” / 144 = s.f. (Length times width divided by 144 = square feet).

Answer:

there is a 13 degree difference from DBC and DAC

 with that you divide 1540 by 13 as you get that 118.461 feet

that means that there is a 118.461 difference from B to C and A to B

so the answer is either 1658.461ft or 1421.539ft I am not sure if that is correct or not but best of luck mate
