Answer:
The answer is x= -4/3
Step-by-step explanation:
3(x-4)=12x
=3x-12=12x
=3x-3x-12=12x-3x
-12=9x
To find x divide both sides by 9.
-12÷9=9x÷9
-4/3=x
Answer:
= 3.29
Step-by-step explanation:
Let call the length needs to be found is q
We have Law of Cosine:
q = 
= 
= 3.29
The length can be found using the Law of Cosines is 3.29
Answer:
step 3 addition: 20 + 9 = 29
step 4 subtraction: 29 - 2 = 27
solution 27
Step-by-step explanation:
since there's no more multiplication or division, you add and subtract from left to right
Answer:
26 is the answer
Step-by-step explanation:
Answer:
Step-by-step explanation:
One
Sin(x) = 15/24 = 0.625
x = sin-1(0.625)
x = 38.68
Two
Cos(x) = 8/11
Cos(x) = .727
x = cos-1(.727)
x = 43.34
Three
Tan(x) = 20/37
Tan(x) = 0.5405
x = tan-1(0.5405)
x = 28.39
Four
Cos(x) = 18/23
Cos(x) = .7826
x = cos-1(0.7826)
x = 38.50
