Answer 1

I think it's 51.5 90% positive!!!

Answer 2

soh cah toa

tan 42 deg = x/35
solve for x by multiplying 35 to both sides

Answer 3

Same as the question i answered earlier, square = 90 degrees, the other angle is 42 degrees, if all the angles in a triangle add up to 180 degrees (which they do) you would get an equation that looks like this...
180-90-42=48 degrees
Angle Z = 48 degrees

Answer 4

ok ty 48 :D

Answer 5

cool

Answer 6

wait your looking for SIDE X

Answer 7

yes

Answer 8

it didn't ask to solve for Z
it is asking for side x

Answer 9

side x is the opposite side in this image and you use the
tangent = opposite/adjacent

Answer 10

then let use the equivalent of angle z
which is 48
tan z = 35/x
tan 48 = 35/x
cross multiply
xtan28 = 35
divide tan 48 both side
x=35/tan48
x=31.51

Answer 11

that is a long shot of solving it

Answer 12

hahaha!!

Answer 13

you don't even need the value of z to solve for x
you already have 42 degrees and a side of 35 units, so you can use 42 degrees as your angle of focus and use 35 since it is adjacent to the angle of focus
thus implementing the TOA, the opposite is the "opposite side," which is whatever across the angle of focus - the x in this case.
following this logic:

tangent = opposite/ adjacent
tangent 42 degrees = x / 35
solve for x
multiply both sides by 35
tangent 42 degrees * 35 = x

Answer 14

just the same answer.. hahah!!
but @ShantelT1 did u get what we mean?

Answer 15

it should be the same answer, but it is the straight-forward way of answering the problem
what you did is also correct, but you went to do extra steps that would pose inefficient when you have to solve under a limited time like during exam

Answer 16

okay lang basta tama

Answer 17

hahahha!! pwede pala tagalog dito eh.. :D

Answer 18

okay so 31.51?

Answer 19

I think you are just waiting for the answer
bad girl... bad bad girl

Answer 20

good girl, @ShantelT1 very good girl, your smarter than the rest of us :D

Answer 21

^hahah!! mean
@ShantelT1
understand the concept :)

Answer 22

I'ts hard, I don't get it...

Answer 24

it becomes hard when you don't devote time to read and practice
