Answer:

x=120°

Step-by-step explanation:

sum of all angles in a triangle is equal to 180

let the unknown angle be

$\alpha$

$60 + 60 + \alpha = 180 \\ \alpha = 180 - 60 - 60 \\ \alpha = 60 \\$

$\alpha + x = 180 \\ x = 180 - \alpha \\ x = 180 - 60 \\ x = 120$

HELP me with this question PLEASE

Anuta_ua [19.1K]

Answer:

YES

Step-by-step explanation:

Why is the classmate correct?

The reason why the classmate is correct is that everything can turn 360 degrees. This means that a square, has to turn 360 degrees, and it does that by doing 90x4. This means that it has 90-degree angles, which turn 4 times. And that makes 360. That's how this is also correct. Because this classmate turned a figure 270 degrees clockwise, and also, 360-270=90, which means that turning that figure 90 degrees counter-clockwise will make it in that same position.

To check whether this is right or not, take an object, probably like a book. Then turn it 90 degrees to counter-clockwise, and note down the position, that the front of the book is now facing left, and the back of the book is now facing right. Then, turn it back to normal position, (back of the book facing you), then, turn it 3 times 90 degrees towards Clockwise, in that way, you can see, that the book turns in the same way it did when you did 90 degrees counter-clockwise!

<h2>I checked this, it's 176 words long.</h2>

Thanks!

Kay has 28 coins which includes nickels and dimes if the total is 2.35$, how many of each coin does Kay have?

BaLLatris [955]

Answer:

19 dimes and 9 nickels

Step-by-step explanation:

Model the situation using two equations, then solve the system.

let n be number of nickels and d be number of dimes.

n + d = 28 <= This equation is about the number of coins.

0.05n + 0.10d = 2.35 <=This equation is about the worth in dollars.

Rearrange n + d = 28.

n = 28 - d

Now we can substitute this equation into the other one.

Sub n =28-d at the "d" variable for the equation 0.05n + 0.10d = 2.35

0.05n + 0.10d = 2.35

Now there is only one variable.

0.05(28 - d) + 0.10d = 2.35 <=distribute this

0.05(28 - d) + 0.10d = 2.35

1.4 - 0.05d + 0.10d = 2.35 <=combine like terms

1.4 + 0.05d = 2.35 <= begin to isolate d

0.05d = 2.35 - 1.4

0.05d = 0.95

d = 0.95/0.05

d = 19

Now that we know d=19, we can substitute it into any equation.

Choose the equation n + d = 28 because the numbers are easier.

n + d = 28

n + 19 = 28 <=isolate n

n = 28 - 19

n = 9

Since n=9 and d=19, Kay has 9 nickels and 19 dimes.

A gift box’s rectangular base has a perimeter of 92 centimeters. The length of the base is one more than twice the base’s width.

kozerog [31]

Assume that the length of the rectangle is "l" and that the width is "w".

We are given that:
(1) The length is one more than twice the base. This means that:
l = 2w + 1 .......> equation I
(2) The perimeter is 92 cm. This means that:
92 = 2(l+w) ...........> equation II

Substitute with equation I in equation II to get the width as follows:
92 = 2(l+w)
92 = 2(2w+1+w)
92/2 = 3w + 1
46 = 3w + 1
3w = 46-1 = 45
w = 45/3
w = 15

Substitute with w in equation I to get the length as follows:
l = 2w + 1
l = 2(15) + 1
l = 30 + 1 = 31

Based on the above calculations:
length of base = 31 cm
width of base = 15 cm
