Answer:Congratulations
Step-by-step explanation:
By applying the formula of trigonometric function the right hand side will
be equal to right hand side which is 1-
/
=cos2x.
Given: 1-/=cos2x.
Taking right hand side first which is cos2x.
We know that cos2x=
Now we will solve the left hand side of the equation give which is
1-/
=1-
/1+
[secant square x minus tangent square x is equal to 1]
By putting both values left hand side and right hand side we will find our solution which is :
1-tan^{2}x/1+tan^{2}x=1-/1+.
Hence proved

Answer: Angles 1 and 3 are adjacent to angle 140. (because they are next to each other)
Angles 1 and 2, 1 and 140, 140 and 3, and 3 and 2 are supplementary (because together they add up to 180 degrees)
Angles 140 and 2 and 1 and 3 are vertical angles because they are across from each other.
This may be a little confusing, so don't be afraid to ask for clarification, but great luck!
a) Jodi's car traveled 38 miles per gallon of gas. We know this because by dividng the amount of miles traveled by number of gallons Jodi has in her car we can find how many miles she travels per gallon of gas.
So our equation would be 456 / 12 = 38
b) The cost per gallon of gas was $3.74. We can find this answer by dividing how much she paid ($44.88) by how many gallons she bought (12).
So our equation would be 44.88 / 12 = 3.74
B) 35x + 15 = 155
E) It will take 4 months to pay off the debt.
Hope this helps you!
