D.
you cannot have a negative amount of rainfall, so the predicted value of -32.4cm doesn't make sense.
Answer:
50ft
Step-by-step explanation:
Hi,
Considering that one side is equal to 38 degrees, we know this isn't a 30 - 60 - 90 triangle.
One of the legs is equal to 40 feet
So, tan(b) = 40/x
tan(38 degrees) is 0.78 round up to 0.8 (if that's what your teacher wants)
0.8 = 40/x
0.8x = 40
x = 50ft
I hope this helps
1) a.30
3) complementary: 12 and 78
supplementary: 102 and 78
All you have to do is multiply 23/4 by 4/3 which gets you 92/12
Simplify that and you get 23/3
