Vertical angles 4x+7 and [5(x-4)] what is the value of x

Mathematics

Answer:

x = 27

Step-by-step explanation:

Vertical angles are congruent.

5(x - 4 ) = 4x +7

5x - 20 = 4x + 7   {Distributive property}

Add 20 to both sides

5x = 4x + 7 + 20

5x = 4x  + 27

Subtract 4x from both sides

5x - 4x = 27

x = 27

Answer:

x = 27

Step-by-step explanation:

vertical angles are congruent , then

5(x - 4) = 4x + 7 ← distribute parenthesis on left side

5x - 20 = 4x + 7 ( subtract 4x from both sides )

x - 20 = 7 ( add 20 to both sides )

x = 27

Finding angles June 23.2020
finlep [7]

Answer:

angle B is 38 degree

Step-by-step explanation:

In triangle ADC,

finding angle C

angle A + angle C = 110 degree (sum of two interior opposite angles are equal to the exterior angle formed)

46 + angle C = 110

angle C = 110 - 46

angle C = 64 degree

In triangle ABC

finding angle B

angle A + angle B + angle C = 180 degree (sum of interior angles of a triangle)

78 + angle B + 64 = 180

142 + angle B = 180

angle B = 180 - 142

angle B = 38 degree

We can use quadratic formula to determine the roots of the given quadratic equation.

The quadratic formula is:

x= \frac{-b+- \sqrt{ b^{2} -4ac} }{2a}

b = coefficient of x term = 4
a = coefficient of squared term = 1
c = constant term = 7

Using the values, we get:

x= \frac{-4+- \sqrt{16-4(1)(7)} }{2(1)} \\  \\ 
x=  \frac{-4+- \sqrt{-12} }{2}   \\  \\ 
x= \frac{-4+-2 \sqrt{-3} }{2} \\  \\ 
x= -2+- \sqrt{-3}

So, the correct answer to this question is option A

??!?!?!?!?!!?!?!?!!?!!!?!!!!?
Nikitich [7]

Answer:

The third option, a rational number

like 1/5 + 2.5 is still rational (but neither irrational nor whole/an integer)

it would be 0.2 + 2.5 = 2.7 btw

or

1/5 + 5/2

= 2/10 + 25/10

= 27/10
