x=2
Learn how to solve it using jedimath on iPad
Answer:
no it is not proportional
Answer: 4.25, 15, and 38.7°
Step-by-step explanation:
Use SOHCAHTOA
Sine is opposite over hypotenuse
Cosine is adjacent over hypotenuse
Tangent is opposite over adjacent
1.) tan(28) = x/8
8*tan(28) = x
x = 4.25
2.) tan(28) = 8/x
8/tan(28) = x
x = 15
3.) tan(x) = 4/5
x = arctan(4/5)
x = 38.7°
Answer:
It is the first one.
Step-by-step explanation:
The desired value will be the solution to the equation ...
... (5 - a) = 20 + (6a - 1)
... 5 - a = 19 + 6a . . . collect terms
... 5 = 19 + 7a . . . . . . add a
... -14 = 7a . . . . . . . . . subtract 19
... -2 = a . . . . . . . . . . . divide by the coefficient of x
The value of the variable is -2.
