Find The Measure Of Angle A

Answers

Answer 1

Answer:

60 degrees

Step-by-step explanation:

All angles of a triangle will add up to equal 180 degrees.

Set up an equation to solve for x:

9x - 3 + 50 + 9x + 7 = 180

Combine like terms

18x + 47 + 7 = 180

18x + 54 = 180

Subtract 54 from both sides

18x = 126

Divide both sides by 18

x = 7

Now plug in 7 for x in the expression for angle A:

9(7) - 3

63 - 3

60

Check work:

60 + 50 + 9(7) + 7 = 180

110 + 63 + 7 = 180

173 + 7 = 180

180 = 180

Correct

Answer:

  23) insufficient number of corresponding sides/angles

  24) insufficient number of corresponding sides/angles

Step-by-step explanation:

In general, you need at least 3 corresponding parts to show triangle congruence. At least one of those must be a side. The attachment shows the ways triangles can be declared congruent. (HL works for right triangles, because we know the right angles are congruent to each other.)

__

23) A side is shown congruent (KL ≅ GH), and we know the vertical angles at J are congruent. However, we need another angle before we can declare the ∆GHJ congruent to anything. (One more side doesn't do it, because the two sides would not be on either side of the angle at J.)

  Reason: insufficient data

__

24) A side is shown congruent (MP ≅ QS), and an angle is shown congruent (∠M ≅ ∠Q). As in the previous problem, we need at least one more angle, or we need to know that MN ≅ QR before we can declare the triangles congruent.

  Reason: insufficient data

At the end of the 3.5 years, how much money in interest alone will Cameron have paid?

When Cameron finally pays off his credit card, how much will he have paid in all?

Answers

Answer:

the interest is $9,676.91 and the future value amount is $19,876.91

Step-by-step explanation:

The computation is shown below;

The future value is

= Present value × (1 + rate of interest)^number of years

= $10,200 × (1 + 0.21)^3.5

=  $19,876.91

Now the interest amount is

= Future value - present value

= $19,876.91 - $10,200

= $9,676.91

Hence, the interest is $9,676.91 and the future value amount is $19,876.91

value of x if 3x+2y=11 and 5x-y=14

Answers

Answer:

3x + 2y = 11

3x + y = 11 - 2

3x + y = 9

x + y = 9/3

x + y = 3

x = 3 - y

5x - y = 14

x - y = 14/5

x - y = 2.8

x = 2.8 + y

14Answer:

3

Step-by-step explanation:

solve for y in first equation

5x-y=14

-y=14-5x

y=5x-14

substitute y value (5x-14) into 2nd equation

3x+2 (5x-14)=11

3x+10x-28=11

How to solve (x+7)(x-9)>0

Answers

Answer:

x < -7, x > 9.

Step-by-step explanation:

Solve for x.

x = -7, 9

From the values of x above, we have these 3 intervals to test.

[tex]x < - 7[/tex]

[tex] - 7 <x < 9[/tex]

[tex]x > 9[/tex]

Pick a test point for each interval.

For the interval x < −7:

Let's pick x=−8. Then, (-8 + 7) (-8 - 9) > 0.

After simplifying, we get 17>0, which is true

Keep this interval.

Let's pick x=0. Then, (0+7)(0-9) > 0.

After simplifying, we get −63 > 0, which is false.

Drop this interval.

For the interval x > 9:

Let's pick x=10. Then, (10+7)(10-9)>0.

After simplifying, we get 17 > 0, which is true

Keep this interval.

Therefor, the answer is x < -7, x > 9.

Answers

Answer:

Total amount pay after 3 week = $147.5

Step-by-step explanation:

Given:

Amount of loan taken = $125

Amount interest per $100 = $6 per week

Find:

Total amount pay after 3 week

Computation:

Amount of interest per week = 125[6/100]

Amount of interest per week = $7.5 per week

Amount of interest in three week = 3 x Amount of interest per week

Amount of interest in three week = 3 x 7.5

Amount of interest in three week = $22.5

Total amount pay after 3 week = Amount of loan taken + Amount of interest in three week

Total amount pay after 3 week = 125 + 22.5

Total amount pay after 3 week = $147.5

What is the slope of the line passing through the points (-8,5) and (7,0)

Answers

Use the formula y2-y1 over x2-x1
Plug the two points in:
5-0 over (-8)-7 = 5 over (-15) = -3
The slope of the line that passes through points (-8,5) and (7,0) is -3

To solve the problem we must know about the slope of a line.

What is a Slope?

A slope is also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

[tex]m = \dfrac{(y_2-y_1)}{(x_2-x_1)}[/tex]

The slope of the line passing through the points (-8,5) and (7,0) is [tex]\dfrac{-1}{3}[/tex].

Given to us

points (-8,5) points (7,0)

Points can be written as,

[tex]y_2 = 0\\y_1 = 5\\x_2=7\\x_1 = -8[/tex]

The slope of a line

We know that the slope of a line whose two points are given is written as,

[tex]m = \dfrac{(y_2-y_1)}{(x_2-x_1)}[/tex]

Substituting the value, we get,

[tex]m = \dfrac{(0-5)}{[7-(-8)]}\\\\m = \dfrac{(0-5)}{[7+8]}\\\\m = \dfrac{(-5)}{[15]}\\\\m= \dfrac{-1}{3}[/tex]

Hence, the slope of the line passing through the points (-8,5) and (7,0) is [tex]\dfrac{-1}{3}[/tex].
