Answer:

135°, 135°, 90°

Step-by-step explanation:

(3/2)90 = 270/2 = 135

OR 3/2 is just 1.5

1.5•90= 135°

Next: 90+45 = 135°

Finally: 2B -90

= 2•90 - 90

= 180 - 90

=90°

These are the angles you need for your other question. Hang in there!

sweet [91]

Answer:

The length of the diagonal is 11.879 units

Step-by-step explanation:

On any rectangle or square, any 2 adjacent sides and the diagonal that connects them makes a right triangle. The diagonal is the hypotenuse of that right triangle, and you can find it using the pythagorean theorem:

a^2+b^2=c^2

where a and b are the sides, and c is the diagonal.

\rightarrow8.4^2+8.4^2=c^2\\\rightarrow70.56+70.56=c^2\\\rightarrow c^2=141.12\\\rightarrow c\approx11.879

Answer:

TOTAL TAX IS: $19.25

TOTAL PRICE IS: $294.25

MONEY LEFT IS: $135.75

Step-by-step explanation:

First, you do a proportion:

?/275 = 7/100

the ?/275 represents how much money in $275

the 7/100 represents 7% (7 hundredths)

then you cross multiply:

275 x 7 = 1925

then you divide:

1925 divided by 100 = 19.25

<em><u>So $19.25 is the tax amount.</u></em>

<em><u></u></em>

To get the total price, you add:

Tax ($19.25) + Cost($275) = $294.25

<u><em>$294.25 is the total amount that Anna has to pay.</em></u>

<u><em></em></u>

To get what Anna has left over, you subtract:

Has($430) - Spend($294.25) = $135.75

<u><em>Anna has $135.75 left.</em></u>

<u><em></em></u>

I hope this helped you a lot!
