What is tan A? http://lv.k12.com/mediaFiles/Ninth_Grade/Math/Unit17844/Lesson69375/VHS_PA_S2_04_L310_LQ_Q1.GIF A) 4/3 B) 4/5 C) 3/4 D) 3/5
if tanA=opposite/adjacent, than tanA=?
What? @severus4ever
the opposite side is 8, the adjacent side is 10, tanA=8/10 and simplify
B
THX SARAH
no problem!
What is sin B? http://lv.k12.com/mediaFiles/Ninth_Grade/Math/Unit17844/Lesson69375/VHS_PA_S2_04_L310_LQ_Q2.GIF Same answer choices
@severus4ever
D
B or D...but i think D
Yup its D. The formula for 'sin' is Opposite/hypotenuse. The hypotenuse is 5 and the opposite is 3. So 3/5= D
What is cos C? http://static.k12.com/calms_media/media/1422500_1423000/1422777/1/3e0ad8d1a34298da1bf1f77ee4c1e5141ff6ca40/MS_PA_131002_171225.jpg A) 77/36 B) 77/85 C) 36/77 D) 36/85
B
im positive!

If tan A = 2, what is the value of x? Round your answer to the nearest tenth. http://lv.k12.com/mediaFiles/Ninth_Grade/Math/Unit17844/Lesson69375/VHS_PA_S2_04_L310_LQ_Q4.gif A. 3.5 B. 5.5 C. 14.0 D. 28.0
so tanA = x/7, if tanA=2, x/7=2, x=14

@severus4ever
if cos(B) = 0.3, x/35=0.3, x=10.5ft B
