find angle sum therom

Answers

Answer 1

Answer:

y = 120°

Step-by-step explanation:

angles in a triangle add up to 180 degrees

180 - (87 +33) = 60

x = 60 degrees

angles on a straight line add up to 180 degrees

180 - 60 = 120

y = 120

Answer 2

Step-by-step explanation:

we know that,

sum of all angles of triangles is equal to 180°

Then,

33° + 87° + x = 180°

x = 180° - 120°

x = 60°

Now,

we know that,

sum of all angles which lies on a straight line is equal to 180°

Then,

x + y = 180°

60° + y = 180°

y = 120°

Hence,

The value of y = [120]°

6. Talayah bought two journals. The second
journal cost $12 more than the price of
the first journal. If she spent $30 on both,
how much was the second journal?
A. $12
B. $16
C. $20
D. $28

Answers

Answer:

C. $20

Step-by-step explanation:

Lets make our equation. "x" will be our first journal, and "4/5x + 12" will be our second journal. So our equation is: x + 4/5x + 12 = 30

Subtract 12 from each side: x + 4/5x = 18

Combine like terms : 1 4/5 x = 18

Divide each side by 1 4/5 : x = 10

Plug in x for the journals-

1 = 10

2 = 4/5 of 10 = 8 + 12 = $20

The vertices of a triangle are, A (2, 5) B (1, 2) C (3, 1),. Find the coordinates of the image after a
reflection in the x-axis, and then a rotation 90° counterclockwise about the origin.

Answers

Answer:

The images are;

A’ (5,2) B’ (2,1) and C’ (1,3)

Step-by-step explanation:

Firstly, we want to reflect across the x-axis

When we reflect a point (x,y) over x-axis, we get (x,-y)

So;

A ( 2,5) becomes (2,-5)

B (1,2) becomes (1,-2)

C ( 3,1) becomes (3,-1)

Then we proceed to rotate 90 degrees counterclockwise about the origin

Here we have;

(x,y) becomes (-y,x)

(2,-5) becomes (5,2)

(1,-2) becomes (2,1)

(3,-1) becomes (1,3)

C ( 3,1) becomes (3,-1)

The cost of a gym membership is $25 per month. There is an initial fee of $40

Answers

Answer:

y = 25x + 40

Step-by-step explanation:

Using the formula, y = mx + b we can find out what this equation would be.

m = the rate of change/slope

b = the y- intercept

25 per month is telling us that this is the rate of change.

Since the $40 is only paid once, you can tell that this is the y intercept.

The equation will look like:

y = 25x + 40

On a graph it would look like:

Let the total cost of a gym membership be y, with the number of months as x.

The total cost would be 40 dollars, the initial fee, plus 25 times the number of months (x).

y = 40 + 25x

It is given that:

Andy spent $46.95 at the grocery store. The cashier gave him $2.97 in change from a $50 bill.

Let x be the change the cashier should have given Andy.

x + 46.95 = 50

x = 50 - 46.95

x = $3.05

Thus, the cashier should have given Andy back $3.05 if Andy spent $46.95 at the grocery store option (c) $3.05 is correct.

The perimeter of a 6-sided figure is 67.74 meters. Two of the sides have the same length. The sum of the other 4 side lengths is 36.4 meters. About how long is each of the same-side lengths?

Answers

31.41 that the answer

Each of the same-side lengths is 15.67.

What is perimeter?

It is the sum of length of the sides used to made the given figure.

We have been given that the perimeter of a 6-sided figure is 67.74 meters. Two of the sides have the same length. And the sum of the other 4 side lengths is 36.4 meters.

Let the same side be a.

The perimeter of the figure = 6 x side

The perimeter of the figure = 2a + 36.4

67.74 = 2a + 36.4

2a = 67.74 - 36.4

2a = 31.34

a =15.67

Therefore, each of the same-side lengths is 15.67.

For the middle square do 3.14 times 4.5²=63.585

For the bottom square do 3.14 times 6²=113.04

Now find the area of the entire thing do 18×12+9+6+3=18×30=540

Finally do 540-the area of the squares 28.26-63.585-113.04= 335.115
