Find the value of x.
T

OX= 2
O x= 3
O x= 33
O x = 52

x=3

Step-by-step explanation:

Angle TRS would be 180-45x as the angle lies on a straight line and we know angles on a straight line add up to 180 degrees

Then I would add the three angles in the triangle and equate it to 180 degrees as angles in any triangle add up to 180 degrees

therefore:

(180-45x)+25x+(57+x)=180

180-45x+26x+57=180

237-19x= 180

237-180=19x

57=19x

57/19=x

3=x

x is correct as when we substitute it in the angles in the triangle, the interior angles for the triangle does add up to 180

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
