Can someone solve then explain the process of solving this?

Answer:

58°

Step-by-step explanation:

<h3>Angle sum property of triangle:</h3>

The sum of all angles of a triangle is 180°.

x + 69 + 55 + x + 78 = 180

x + x + 69 + 55 + 78 = 180

Combine like terms,

2x + 202 = 180

Subtract 202 from both sides,

2x = 180 - 202

2x = -22

Divide both sides by 2,

x = -22/2

x = -11

∠A = x + 69

= -11 + 69

$\sf \boxed{\angle A= 58^\circ}$

What is the answer to this question?

enot [183]

Answer:

X = 20.5

the equation

x+5*x-2=44

combine like terms

2x+3=44

and so on....

3-44=41

41/2 = 20.5

Now x=20.5

PLEASE HELP ASAP!!!!

Answer:

a = -4

b = 3

c = 6

Step-by-step explanation:

x^2 + 8x = 38

We take the coefficient of the x term

Divide by 2 and then square it

8/2 =4

4^2 = 16

Add 16 to both sides

x^2 +8x + 16 = 38 + 16

x^2 +8x +16 = 54

Take b/2 and use it in the the (x+b/2)^2

(x+4)^2 = 54

Take the square root of each side

sqrt((x+4)^2) = ± sqrt(54)

x+4 = ± sqrt(54)

Subtract 4 from each side

x+4-4 = -4 ± sqrt(54)

x = -4 ± sqrt(54)

Simplify the square root

x = -4 ± sqrt(9*6)

x = -4 ± sqrt(9) sqrt(6)

x = -4 ± 3 sqrt(6)
