Answer:

Step-by-step explanation:

The angle whose sine is 5/12 = 22.62 degrees and in Quadrant II it is

180 - 22.62 degrees

The angle whose tan is (5/12) = 22.62.

So we can write α as 180 - α and β as α.

sin (α+β) = sin ( 180 - α = α) = sin 180

= 0.

In a rectangle, opposite sides are equal so you can multiply the side lengths by 2 and add them so 16(2)+34(2) and yu get 32+68. The perimeter is 100

NEED HELP!!!

AnnyKZ [126]

Answer:

see explanation

Step-by-step explanation:

(1)

$\frac{6}{2}$ = $\frac{4}{p}$ ( cross- multiply )

6p = 8 ( divide both sides by 6 )

p = $\frac{8}{6}$ = $\frac{4}{3}$

(2)

$\frac{n}{4}$ = $\frac{8}{7}$ ( cross- multiply )

7n = 32 ( divide both sides by 7 )

n = $\frac{32}{7}$

(3)

$\frac{5}{3}$ = $\frac{x}{4}$ ( cross- multiply )

3x = 20 ( divide both sides by 3 )

x = $\frac{20}{3}$
