Mathematics

Answer:

Answer is - 2.

Step-by-step explanation:

(f+g) (x)=f(x) +g(x)=x^2 -2x +6x+4

=x^2 +4x+4=0

If x=-4, then (f+g) (-4) =16-16+4=4

if x=-2, then (f+g) (-2)=4-8+4=0

\huge\underline\color{pink}{Answer ☘}

angle \: sum \: property \: of \: a \: triangle  \\ states \: that \: the   \: sum \: of  \\  all \: the \: three \: angles \: of \: a \: triangle \: is  \\ equal \: to \: 180°

therefore~

63 + (x + 17) + (4x - 5) = 180° \\ 63 + x + 17 + 4x - 5 = 180° \\ 5x  + 75 = 180 \\ 5x = 180°  -  75 \\ 5x = 105° \\ x =  \frac{105}{5}  = 21°

therefore the measure of all the angles are..

∠1 = 63°

∠2 = ( x + 17 ) = ( 21 + 17 ) = 38°

∠3 = ( 4x - 5 ) = ( 84 - 5 ) = 79°

<h3>thus \: the \: measure \: of \: the \: largest \\ angle\: is \: 79°</h3>

hope helpful~

Determine the value of x for which rls if<br> .<br> m2i = 80 - X; and<br> mz2 = 90 - 2x<br> .
Slav-nsk [51]

Answer:

  x = 10

Step-by-step explanation:

For the lines to be parallel, the two angles must have the same measure:

  80 - x = 90 - 2x

  x = 10 . . . . . . . . . add 2x-80

The value of x must be 10 to make the lines parallel.
