Answer:
to make sure you understand the question
Step-by-step explanation:
Isnt it 4x-2 ?? i mean it does say "find" AB...
The last one HOPE THIS HELPS!!!!
Must do multiplication first....
-2/5 - 3/7 x 7/10
-2/5 - 21/70 (I'll reduce 21/70)
-2/5 - 3/10
Now you have to find a common denominator and subtract
-35/50 = -7/10......is what I get
Sin 35 = x/15
x = sin 35*15
x = 8.6 cm
