Answer:
x ≈ 63.27
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan49° =
=
=
( multiply both sides by 55 )
55 × tan49° = x , then
x ≈ 63.27 ( to the nearest hundredth )
If you follow PEMDAS your answer would be 3.6.
2.2x and 4.4 have a GCF of 2.2. So, you can factor that out like so:
2.2x+4.4 = 2.2*x+2.2*2 = 2.2(x+2)
Hope this helps!
