Those two angles total equal 180 degrees. 
Since we know the first angle equals 155 degrees.
180-155+25.
ABC is 25 degrees.

< CBD = 155
< CBD and < ABC are supplementary angles which, when added = 180

so...< CBD + < ABC = 180
           155 + < ABC = 180
           < ABC = 180 - 155
           < ABC = 25 <===

Ariane borrows $300 on a 5−year loan. She is charged 5% simple interest per year. How much interest is she charged for 5 years?
AnnyKZ [126]

Answer:

Interest = $75

Total to pay back = $375

Step-by-step explanation:

The total amount she will have to pay back is found by the formula:

= Amount borrowed * (1 + rate * years)

= 300 * ( 1 + 5% * 5)

= $375

The interest is therefore:

= Amount to be paid back - Amount borrowed

= 375 - 300

= $75

What is the answer to this?
Yanka [14]
DEF= 6 ft^2

A= 1/2*b*h

Plug in what you know.

6= 1/2*4*h

Multiply like terms. 

6=2*h

Divide 2 on both sides. 

3=h

If the base of ABC= 12

12/4=3

3*3=9

A= 1/2*b*h
A= 1/2*12*9
A= 1/2*84
A= 42

The area of ABC is 42 ft^2

I hope this helps!

There will be 18 girls in a group of 16 boys.

you divide 72 by 16 and get 4.5.
then you divide 81 by 4.5 and get 18.

That is how you get 18 girls in a  group of 16 boys.

Hope that helped.
