Solve Triangle DEF. - Math

Brrunno [24]

Answer:

$p = 52.942259755149776$

Step-by-step explanation:

This is basic trigonometry.

$\cos(39) = \frac{e}{22}$

$e = \cos(39) \times 22$

$\sin(39) = \frac{d}{22}$

$d = \sin(39) \times 22$

And finally perimeter (p):

$p = 22 + e+ d$

There are about 76.9 million pet dogs and 87 million pet cats in the United States. The number of pet dogs is what percent less

Dmitriy789 [7]

Answer:

The number of pet dogs are 11.61% less than the number of pet cats.

Step-by-step explanation:

Number of pet dogs in the United states = 76.9 million

Number of pet cats in the United states = 87 million

Difference between the number of cats and dogs :

$=87 million- 76.9 million = 10.1 million$

Percentage of number of pet dogs less than pet cats:

$=\frac{\text{Difference}}{\text{Number of cats}}\times 100$

$=\frac{10.1 million}{87 million}\times 100=11.61\%$

The number of pet dogs are 11.61% less than the number of pet cats.

pogonyaev

Answer:

3.5

Step-by-step explanation:

so this triangle is symmetrical by AA. so x would be symmetrical to 7, and 2.5 is symmetrical to 5.

$\frac{x}{2.5}$ = $\frac{7}{5}$

x×5=5x

2.5×7=17.5

5x=17.5

x=17.5/5

x=3.5
