Answer:
119 degrees
Step-by-step explanation:
The measure of EAC is 119 because 62 + 57 = 119.
Then, EAC and BAD are vertical angles, so they are equal.
Therefore, BAD = 119 degrees
Answer:
9
Step-by-step explanation:
6/2(1+2)
6/2(3)
6/2=3
3(3)=9
Since this is a right triangle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.
Remember: SOH-CAH-TOA
Looking from angle I, we know the opposite side and the hypotenuse. Therefore, we should use sine.
sin(I) = 
To solve, you can use your calculator and the inverse sine function (sin^-1).
I = sin^-1(
)
I = 61 degrees
Hope this helps!
Range I think I may be wrong ?
The cost would be $4.74. 3.95 times 0.2 is 0.79. Add that to 3.95 and get 4.47
