Answer:
5) 34° 6) 17° 7) ? 8) ? 9) 50° 10) ? You do 7, 8 and 10
Step-by-step explanation:
Let x = the measure of the unknown angle in each case
5) tan x = 10/15 arctan 10/15 = 34
6) tan x = 10/32 arctan 10/32 = 17
7) tan x = 3/8 You do this one
8) tan x = 4/6 You do this one
9) sin x = 26/34 arcsin 26/34 = 50
10) tan x = 20/37 You do this one
You need to learn the definitions of sin, cos, tan, i.e sin x = opp/hyp
cos x = adj/hyp and tanx = opp/adj
opp means opposite side of x
adj means the leg of the right triangle that is a side of x
hyp means the hypotenuse of the right triangle
