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~

Nutka1998 [239]

Answer:

x=5/13

Step-by-step explanation:

2/3+7/2=9x+5/6+4x

lcm of 2,3,6=6

2/3=4/6      7/2=21/6       5/6=5/6

4/6+21/6-5/6=9x+4x

30/6=13x

5=13x

x=5/13

The ratio of dogs to cats at a local animal shelter is 13/25. Which statement must be true?
Ivan

<em>Option:</em>

<em>a. for every 13 dogs, there are 25 cats. </em>

<em>b. there are twice as many cats as dogs at the shelter. </em>

<em>c. the shelter has more dogs than cats. </em>

<em>d. there are 25 animals in the shelter.</em>

Answer:

a. for every 13 dogs, there are 25 cats.

<em></em>

Step-by-step explanation:

Represent Dogs with D and Cats with C;

So;

\frac{D}{C} = \frac{13}{25}

By comparison:

D=13

C = 25

This implies that:

For every 13 D, there are 25 C

Hence: Option A is true
