On a piece of paper, use a protractor and a ruler to construct △ABC with AB=6 cm , m∠A=80° , and m∠B=50° .
Svetllana [295]
The correct answer for this question is this one:

<span>On a piece of paper, use a protractor and a ruler to construct △ABC with AB=6 cm , m∠A=80° , and m∠B=50° .

What is AC ?

3 cm
<u>6 cm</u>
9 cm
12 cm</span>

If you try to draw the triangle, it forms an isosceles triangle.
side AB has a length of 6cm. Side AB = Side AC. So the length of Side AC is also 6 cm.

Hope this helps answer your question and have a nice day ahead.

Answer:

280 ft squared

Step-by-step explanation:

To find the area of the nonshaded portion, we can find the area of the entire floor and then subtract the shaded area.

The total area is that of a rectangle: 30 * 15 = 450 ft squared.

Now, the shaded region is made up of a rectangle and a triangle.

- The rectangle has length 8 and width 10, so its area is 10 * 8 = 80 ft squared.

- The triangle has base 12 and height 15, so using the area of a triangle formula: A=(bh)/2 (where b is the base and h is the height) = (12 * 15)/2 = 180/2 = 90 ft squared.

- The total shaded region is: 80 + 90 = 170 ft squared

Subtract 110 from 450: 450 - 170 = 280 ft squared.

Thus, the answer is 280 ft squared.

Hope this helps!

I don't now how too do this
shusha [124]
The shortest hand stands for one hour. to find the hour look to where the shortest hand is pointing to or has not passed yet.

the long hand stands for minutes. multiply 5 by the number that the longest hand is pointing to or has not passed yet, then count how many dashes after that number to find the minute. 12 stands for 0 in minutes.

1) 4:03
2)8:50
3)11:05
4)6:49
5)12:20
6)9:57
7)3:01
8)2:49
9)1:14

don't worry, i had trouble with this too when i was younger. you will get it eventually. hope i helped! ;)

The initial population of a town is 2600, and he grows with the doubling time of 10 years. What will the population be in 12 yea
ira [324]
I think it would be 5,720, because if you figure every year the population grows 260, then 2600x2 would be doubled then add the 2 years missing so add 260+260. It would equal 5,720.
