Answer:
14
Step-by-step explanation:
Answer:
x = -5.85
Step-by-step explanation:
Solve the equation
1)
Subtract -2.7 on both sides by doing the inverse operation.
2)
Multiply both sides by -9/2 to cancel out -2/9x, so that you can isolate "x" by itself.
3)
For L to be parallel to M, then 7x - 7 must be equal to 4x + 14, as they are alternate angles along 'parallel lines'.
Thus, 7x - 7 = 4x + 14
3x = 21
x = 7
Answer:
tanx·secx
Step-by-step explanation:
To simply this, you can begin by factoring sin x out of the numerator to become:
Now, using Pythagorean Trig Identities, we know that sin²x+cos²x equals 1. We can substitute this to make the equation become:
First of all, we can convert to tanx. However, we have a remaining which, using reciprocal identities, will become sec x.
Finally, we get our answer as tanx·secx.
