you are making a picture frame in your shop class. two peices of wood are cut to form complementary angles so they fit fit toget

Andrews [41]

Two angles are complementary when their sum is equal to 90°.

So, ( 2x + 39 ) + ( 7x - 21 ) = 90°

9x + 18° = 90°

x = 8°

Putting value of x in the angles given :

( 2x + 39 )° = 2(8°) + 39° = 55°.

( 7x - 21 )° = 7(8°) - 21° = 35°.

Therefore, the angles are 55° and 35°.

Hence, this is the required solution.

Find m∠B. Put the answer below.<br> m∠B =

kkurt [141]

$\huge\underline{Answer -}$

we know that

$tan\:θ \:= \frac{perpendicular}{base}\\$

thus in the question ,

$\tan(B) = \frac{perpendicular}{base} \\ \\ \tan(B) = \frac{\cancel{24} \sqrt{3} }{\cancel{24}} = \sqrt{3} \\ \\ \tan(60) = \sqrt{3}$

therefore , m∠B = 60°

hope helpful~

spencer took 21$ with him to the mall. At the music store, he spent 2/3 of his money on a DVD, he spent 1/4 of what he had left

Sunny_sXe [5.5K]

Answer:

$5.25 Dollars

Step-by-step explanation:

I know that if you divide 21 by 3 you get 7. So, 2/3 of 21 is 14. He spent 14 dollars at the music store. This means that he has 7 dollars left. From here he spend 1/4 of 7 dollars on a drink. 1/4 of 7 is $1.75. This means that he has 5.25 dollars left after he bought the drink! :)

<em>Hope this helped! :)</em>
