You conclude a triangle is 7 cm long and 3.5 tall. use these measurements to estimate the six trigonometric ratios of θ. (round your answers to two decimal places.)

Step-by-step explanation:

The Pythagorean theorem tells you the length of the hypotenuse of the triangle:

  AC² = AB² + BC²

  AC² = (7 cm)² +(3.5 cm)²

  AC = √(61.25 cm²) = 3.5√5 cm ≈ 7.8262 cm

The mnemonic SOH CAH TOA reminds you of the definitions of three of the trig functions. The remaining functions are their reciprocals.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
