Answer:

x is approximately 48.2.

Step-by-step explanation:

Use the trig function of cosine, or adjacent over hypotenuse.

cos theta = adjacent / hypotenuse

Substitute variables.

cos x = 10 / 15

Apply inverse cosine to both sides.

x = cos^-1(10/15)

Evaluate.

x ≈ 48.2

Answer:

x ≈ 48.2°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos x = \frac{adjacent}{hypotenuse} = \frac{10}{15} , then

x = cos^{-1} (\frac{10}{15} ) ≈ 48.2° ( to the nearest tenth )

Mashutka [201]

Answer:

{ \tt{ \blue{  - {3x}^{2} + 4x + 4 }}}

Step-by-step explanation:

{ \tt{3x -  {2x}^{2}  + 4 -  {x}^{2} + x }} \\

» Collect second degree terms (x² coefficients) together and first degree terms (x coefficients) and constants

= { \tt{( - 2 - 1) {x}^{2} + (3 + 1)x + 4 }} \\  = { \boxed{ \tt{ \:  -  {3x}^{2}  + 4x + 4}}}
