FInd the approximations to at least two decimal places for the coordinates of Point Z in the figure below. The angle theta or Q

is -80 degrees and the radius is 11.
Z = ?

Also if you can explain to me, that would be great.

Check the picture below.

thus the rectangular coordinates are [ 11cos(-80°), 11sin(-80°) ].

make sure your calculator is in Degree mode.

What is the value of X

Volgvan

Answer:

Step-by-step explanation:

it's another one of those similar triangles

it's easier to see this one.

t /c = u / b

where

t = 7x + 3

c = 27

u = 35

b = 21

plug in the knowns

7x + 3 / 27 = 35 / 21

7x + 3 = 27 ( 35 / 21 )

7x + 3 = 9 ( 35 / 7 ) ( divided by 3 )

7x + 3 = 9 ( 5) ( 7 into 35 =5 )

7x + 3 = 45

7x = 45 - 3

7x = 42

x = 6

I checked it, the ratio is 1_2/3 :) for both, but you can check it too
