Answer:
x ≈ 34.28
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan29° =
=
( multiply both sides by x )
x × tan29° = 19 ( divide both sides by tan29° )
x =
≈ 34.28 ( to the nearest hundredth )
-11y-9=2
-11y=11
y=-1
4[-1]+1
-4+1=-3
-3 is your answer.
Answer: B
4x^{6} - 2x^{5} + 4x^{3} -x^{2} +4x
Step-by-step explanation:
Let's solve
Using Pythagorean theorem
