Find x for the shown triangle.

Option (1)

Step-by-step explanation:

In the given triangle ABC,

By applying tangent rule (tan rule) in the given right triangle,

tan B =

tan B =

tan 60° =

x =

x =

x =

x =

Therefore, measure of the adjacent side AC = √3 unit

Option (1) will be the answer.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
