Answer:
Tan B = 12/5
Sin B = 12/13
Cos B = 5/13
Step-by-step explanation:
sine B = opposite (12)/hypotenuse (13)
= 12/13
Cosine B = adjacent/hypotenuse
= 5/13
Tangent B = opposite/adjacent
= 12/5
Here is a picture that can always help you with the three trig ratios.
1.even
2.neither
3.odd
4.neither
60 degrees
angle 120 divided by two gives you 60 degrees or the angle of one slice
answer of second question 12x-6 =6(2x-1)
12x-6
= 6(2x-1) take the common
=Answer=6(2x-1)
3x+11 = 5x - 8
-2x = -19
x = 9.5
