Answer:
second option
Step-by-step explanation:
Using the rule of radicals
× ⇔
Simplifying the radicals
=
= × × ×
= 3 × × x ×
= 3x
-------------------------------
=
= × × ×
= 2 × × x ×
= 2x
---------------------------------------
Thus
3 × 3x - 2 × 2x
= 9x - 4x
= 5x
Answer:
AB ≈ 7.08
Step-by-step explanation:
Cos θ = adjacent / hypotenuse
where θ = 20° , adjacent = 7 and hypotenuse = AB
cos 20 = 7 / AB
cos 20 × AB = 7
AB = 7/Cos 20
AB = 7 / 0.989
AB = 7.077
AB ≈ 7.08
