Question

Determine the measure of angle x and angle z to the nearest tenth og a degree

Answer 1

\[\tan = opposite/adjacent\]
\[\tan^{-1} =opposite/ adjacent\]
Tan-1 is for solving angles and tan is for solving length

Answer 2

tan inverse 2

Answer 3

experimentx i dont get it

Answer 4

Your definition of inverse tangent is wrong:
\[\tan^{-1} \neq opposite/adjacent\]
opposite =12
adjacent=6
tan z=2\[z=\tan^{-1}2=1.1 rad\]

Answer 5

ok.... that didnt solve my question

Answer 6

x+y+z=pi/2 for all triangles so
\[x=\pi-1.1-\pi/2=0.47rad\]

Answer 7

sorry, I meant
x+y+z=pi for all triangles so...

Answer 8

you need the angles, right? so those are your solutions
z=1.1 radians
x=0.47 radians

Answer 9

tan Z = opposite/adjacent
Z = tan inv (opposite/adjacent)

Answer 10

Need more help Baily?
If so tell me where you got lost.

Answer 11

experiment x that makes sense
but can you put numbers in to show me step by step on the equation

Answer 12

like you have to be sure to use the trigonomic ratios kk?

Answer 13

like that radian stuff. i dont know

Answer 14

opposite =12
adjacent=6
tan z=12/6=2
z=arctan(2)=1.1 (arctan is the same as inverse tan)
because it is a triangle x+y+z=pi, right? We know y=pi/2, so solving for x gives:
x=pi-pi/2-z=pi/2-1.1=0.49 radians
if you don't understand radians I can't see how you can do trigonometry.

Answer 15

a circle has 2(pi) radians =360 degrees
almost all trig and higher math is done with radians. If you need to convert to degrees use the conversion
pi radians=180 degrees

Answer 16

You need only to find one. I would choose z, tanz=opp/adj
tan z=12/6=2.0
angle z= arc tan 2.0=63.43 degrees
angle x=90 -63.43 degrees.

Answer 17

so when you subract 90-63.43 degrees you get your awnswe

Answer 18

yes for angle x.

Answer 19

what abo8ut z

Answer 20

angle z was calculated to be 63.43 degrees

Answer 21

See the post above. to see how z was calculated.

Answer 22

The problem was requesting the answer in degrees. You can do as TuringTest suggested and then convert radian to degrees.

Answer 23

ok thanks
