Answer:

The value of x is 5

Step-by-step explanation:

In triangle ABC

Using Angle Sum property of triangle to find the value of x.

Angle Sum property: The sum of all angles of a triangle is 180.

\angle A+\angle B+\angle C=180^{\circ}

91^{\circ}+(10x-4)^{\circ}+(8x+3)^{\circ}=180^{\circ}

10x+8x+90=180

18x=180-90

x=5

Hence, The value of x is 5

Answer:

x = 5 is the right answer.

Step-by-step explanation:

As we know sum of all angles in a triangle is 180°.Therefore in this question we will form an equation.

Sum of all the angles of a triangle = 180

91 + 10x - 4 +8x +3 = 180

90 + 18x = 180

18x + 90 - 90 = 180 - 90

18x = 90

x = 90÷18 = 5

Therefore x = 5 is the right answer.

Find the values of x,y,z. This diagram is not a scale.
Serjik [45]

Important:
                             The sum of the three angles inside
                              every triangle is always 180°.


First, look at the left triangle alone.
Two of its angles are 46° and 58° .  (46° + 58° ) = 104°
That leaves (180° - 104° ) = 76° degrees for the third angle.
The third angle in that triangle is 'x'. 
                                                         x = 76° .

At the point where 'x' and 'z' come together:
'x' and 'z' are a "linear pair".
Placed side-by-side, they form a straight line.
So (x + z) = 180° .
But  x = 76°.
So z = (180° - 76°).              z = 104° .

Now look at the the skinny triangle on the right alone.
The angle at the top is 13°, and  z = 104°. 
(13° + 104°) = 117° . 
That leaves (180° - 117°) = 63° for the third angle.
'y' is the third angle.
                                                 y = 63° .

If g(x) = x+1/ x-2 and h (x) =4 - x , what is the value of ( g*h) (-3)?
Lapatulllka [165]

<u>Answer:</u>

g (h (x) ) = 5/8

<u>Step-by-step explanation:</u>

We are given the following two functions and we are to find the value of g ( h ( - 3 ) ):

g ( x ) = \frac { x + 1 } { x + 2 }

h ( x ) = 4 - x

Firstly, we need to find the function :

g ( h ( x ) ) = \frac { ( 4 - x + 1 ) } { ( 4 - x - 2 ) } = \frac { 5 - x } { 2 - x }

Now substituting the value x=-3 in it:

g ( h ( x ) ) = \frac { 5 - (-3) } { 2 - (-3) }

g (h (x) ) = 5/8
