What is the value of this x? i feel like it's 90 just double checking

x=56

Step-by-step explanation:

There are 3 angles in the triangle

x, 60 and the unknown angle we will call y

y  and 2x+4 make a straight line, so that adds to 180

y + 2x+4 = 180

Solve for y

y = 180 - (2x+4)

y = 180 -2x-4

y = 176 -2x

The three angles in a triangle add to 180

x + 60 + y = 180

Substitute in for y

x + 60 + 176 -2x = 180

Combine like terms

-x +236 = 180

Subtract 236 from each side

-x+236-236 = 180-236

-x = -56

Multiply by -1

x = 56

c is the final : )

i think it is c, not positive though
