Question

in triangle determine value of a

Answer 1

use trigonometry

cos x = adjacent / hypotenuse

Answer 2

the angle is 35 and you are given the length of the adjacent side

Answer 3

35=a/5
5*.82=a
4.1=a

Answer 4

no thats wrong

a = hypotenuse
so its

cos 35 = adjacent / hypotenuse = 5 / a

a * cos 35 = 5

a = 5 / cos 35

Answer 5

6.1 got it thanks

Answer 6

yw

Answer 7

this will help you remember the trig ratios

SOH-CAH-TOA

sine = opp / hyp
cos = adj/hyp
tan = opp/adj

Answer 8

yes, I have that but it is still confusing thanks
